Claims
- 1. A pyrazolopyrimidine compound of formula I in whichY is NR2; R1 and R2 together with the nitrogen atom to which they are bonded form a radical selected from the group consisting of 4-me-thylpiperidin-1-yl, 2-methylpiperidin-l-yl, 5, 6-dihydro-2H-pyridin-1-yl, 2-ethylpiperidin-1-yl and azepan-1-yl; m is 0 or an integer from 1 to 4; L each independently is halogen, nitro, C1-C10-alkyl, C1-C10-alkoxy; X is halogen.
- 2. The compound defined in claim 1, in which L1 is fluoro, L2 is hydrogen or fluoro, L3 is hydrogen, fluoro or methoxy and L4 is hydrogen, fluoro, chloro or methyl, and #denotes the link to the pyrazolopyrimidyl moiety.
- 3. The compound defined in claim 2, in which m is 1, 2 or 3, and L4 is fluoro, chloro or methyl.
- 4. A process for preparing the compound of formula I defined in claim 1, which comprises reacting 5-aminopyrazole with a 2-phenyl malonic acid ester of formula II, wherein R denotes C1-C6-alkyl, under alkaline conditions, to obtain a compound of formula III, subsequently treating the compound of formula III with a halogenating agent to obtain a compound of formula IV then treating the compound of formula IV with an amine of formula VR1—Y—M V in which H represents a hydrogen atom or a free or complexed metal atom, to obtain the compound of formula I.
- 5. A composition suitable for controlling phytopathogenic fungi, comprising a solid or liquid carrier and the compound of formula I defined in claim 1.
