- 9. The method of claim 2 wherein R is alkyl of 1 to 6 carbon atoms and R.sup.1 is phenyl substituted with 1 to 2 of the same or different substituents selected from fluoro, chloro, bromo, nitro or alkyl of 1 to 4 carbon atoms.
- 10. The method of claim 9 wherein X is chloro, R is methyl and R.sup.1 is 3,4-dichlorophenyl.
- 11. The method of claim 9 wherein X is chloro, R is methyl and R.sup.1 is p-fluorophenyl.
- 12. The method of claim 9 wherein X is chloro, R is ethyl and R.sup.1 is p-fluorophenyl.
- 13. The method of claim 9 wherein X is chloro, R is methyl and R.sup.1 is p-chlorophenyl.
- 14. The method of claim 3 wherein R is p-chlorophenyl and R.sup.1 is methyl.
- 15. The method of claim 3 wherein R is alkyl of 1 to 6 carbon atoms and R.sup.1 is phenyl substituted with 1 to 2 of the same or different substituents selected from fluoro, chloro, bromo, nitro or alkyl of 1 to 4 carbon atoms.
- 16. The method of claim 15 wherein R is methyl and R.sup.1 is p-chlorophenyl.
- 17. The method of claim 15 wherein R is methyl and R.sup.1 is 2,5-dichlorophenyl.
- 18. The method of claim 15 wherein R is ethyl and R.sup.1 is 2,5-dichlorophenyl.
- 19. The method of claim 15 wherein R is methyl and R.sup.1 is p-bromophenyl.
