Compounds of the formula (I) in accordance with the present invention may readily be prepared by a process provided by the invention and illustrated below. The process comprises the steps of reacting a compound of formula (IV) ##STR5## [wherein R.sup.1 and R.sup.2 are as defined and R.sup.7 is a leaving group], with a compound of formula (V) ##STR6## [wherein R.sup.3, A and R.sup.4 are as defined], and optionally salifying the resultant compound.
The reaction is an analogy procedure and the nature of the leaving group R.sup.7 is not critical. R.sup.7 can be, for example, a halogen atom or an alkylthio group, or it can be any other leaving group employed for an analogous reaction. The present reaction may be performed under per se known conditions, suitably in the presence of a base and in the presence or absence of a solvent.
Where a solvent is used, there is no special limitation provided it does not interfere with the reaction. Suitable solvents include, for example, chlorinated or non-chlorinated aromatic, aliphatic or alicyclic hydrocarbons (for example, benzene, toluene, xylene, methylnaphthalene, petroleum ether, ligroin, hexane, chlorobenzene, dichlorobenzene, methylene chloride, chloroform, dichloroethane, trichloroethylene or cyclohexane), ethers (for example, diethyl ether, ethylene glycol dimethyl ether, tetrahydrofuran or dioxane), ketones (for example, acetone or methyl ethyl ketone), alcohols (for example, methanol, ethanol or ethylene glycol), amides such as N,N-dimethylformamide or N.N-dimethylacetamide; higher alcohols; other polar solvents such as dimethylsulphoxide and pyridine; or mixtures of such solvents with each other or with water.
Examples of suitable bases employed in preferred embodiments of the present process include organic bases such as triethylamine, pyridine or N,N-diethylaniline, and inorganic bases such as sodium hyroxide, potassium hydroxide, sodium carbonate or potassium carbonate.
The reaction temperature is not critical, but will usually be from above ambient temperature up to the reflux temperature of the solvent used; it is preferable to perform the reaction with heating in order to shorten the reaction period. Alternatively, when no solvent is used, the reaction may be performed by melting reactants with heating, typically for instance to about 200.degree. C. More generally the reaction is usually carried out at from 100.degree. to 200.degree. C.
Upon completion of the reaction, the desired product may optionally be purified by conventional means, such as by the use of recrystallization and/or chromatographic techniques.
In accordance with one aspect of the process of this invention, a compound of formula (II): ##STR7## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.5 and A are as defined above) is prepared. The process then comprises reacting a compound of formula (VI) ##STR8## [wherein R.sup.1 and R.sup.2 are as defined and R.sup.9 is selected from halogen atoms and methylthio groups], with a compound of formula (VII) ##STR9## [wherein R.sup.3, A and R.sup.5 are as defined], and optionally salifying the resultant compound.
In accordance with another aspect of the process of this invention, a compound of formula (III): ##STR10## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.6 and A are as defined above) is prepared. The process then comprises reacting a compound of formula (VIII) ##STR11## [wherein R.sup.1 and R.sup.2 are as defined and X is a halogen atom], with a compound of formula (VII) ##STR12## [wherein R.sup.3, A and R.sup.6 are as defined], and optionally salifying the resultant compound.
In general, the reaction conditions will preferably as previously described; however for the preparation of compounds of formula (II) using a compound (VI) where R.sup.9 is a methylthio group the reaction is preferably performed in an inert organic solvent with heating. The solvent is then preferably selected from: aromatic hydrocarbons such as toluene and xylene; chlorinated aromatic hydrocarbons such as chlorobenzene, dichlorobenzene and chlorotoluene; ethers such as dioxane; amides such as N,N-dimethylformamide and N,N-dimethylacetamide; higher alcohols; dimethylsulphoxide and pyridine. More preferably the solvent is one having a boiling point of from 100.degree.-200.degree. C., for example N,N-dimethylformamide, N,N-dimethylacetamide or dimethylsulphoxide.
Acid addition salts of compounds of formula (I) may readily be prepared by introducing an acid into the reaction mixture, then by distilling off any solvent.





The preparation of compounds according to the invention is illustrated by the following Preparative Examples.
PREPARATIVE EXAMPLE 1

APPLICATION EXAMPLE 5
Activity against powdery mildew in cucumbers
Cucumber seedlings (variety Sagamihanjiro) were planted two per 12 cm diameter pot and used as host plants when the first leaf was fully grown and open. Each test group of three pots was treated with each of the active compounds by spraying on an aqueous suspension containing 500 ppm of the active compound at the rate of 30 ml per 3 pots.

Activity against the anthracnose in cucumbers
Cucumber seedlings (variety Sagamihanjiro) were planted two per 12 cm diameter pot and used as host plants when the first leaf was fully grown and open. Each test group of three pots was treated with each of the active compounds by spraying on an aqueous suspension containing 500 ppm of the active compound at the rate of 30 ml per 3 pots.
