<p>1500576 Amides CIBA-GEIGY AG 8 April 1975 [9 April 1974 7 March 1975] 14379/75 Heading C2C The invention comprises compounds of the formula wherein R 1 represents a halogen atom or an alkyl or alkoxy group of 1 to 4 carbon atoms, R 2 represents a hydrogen or halogen atom, an alkyl group of 1 to 3 carbon atoms or an alkoxy group of 1 to 4 carbon atoms, R 3 represents a hydrogen atom, or a methyl or ethyl group, R 4 represents an alkyl group of 1 to 6 carbon atoms unsubstituted or substituted by cyano (-CN) or rhodano (-SCN), an alkenyl group of 2 to 5 carbon atoms or a cycloalkyl group of 3 to 7 carbon atoms, R 5 represents a hydrogen or halogen atom, or an alkyl group of 1 to 3 carbon atoms, and R 6 represents a hydrogen atom or a methyl group, the total number of carbon atoms in the substituents R 1 , R 2 , R 5 and R 6 not exceeding 8. The compounds may be prepared by acylating a compound of the formula with a compound of the formula HO-CO-R 4 or with a reactive derivative thereof, or by converting a compound of the formula with butyl lithium or sodium hydride into the corresponding alkali salt which is then reacted with a compound of the formula where Hal is halogen or another easily removable radical, or by reacting the compound of Formula IV with Hal-CH(CH 3 )-COOR 3 in the presence of an alkali carbonate.</p> |
