Abstract

Compounds of formula (II) where R1 is in the para or meta position and is (A); R2 and R3 are each independently selected from hydrogen, nitro, C1-6alkyl, C3-6cycloalkyl, C2-6alkenyl, C2-6alkynyl, C1-4alkoxyl, C1-6alkylamino, C1-6dialkylamino, C1-6akylC1-4alkoxyl, C1-6alkylaminoC1-6alkyl, amino, cyano, halogeno, trifluoromethyl, —CO2R12 and —CONR12R13, where R12 and R13 are independently selected from hydrogen or C1-6alkyl, or R2 and R3 together with the phenyl to which they are attached form a 9 or 10 membered bicyclic ring system; R4 is C1-4alkyl; R5 is selected from hydrogen and C1-4alkyl; R6 is selected from C1-6alkyl, C1-4alkyl(C4-6)cycloalkyl, C1-6alkyl(C1-6)alkoxyl, C1-6alkylS(C1-6)alkyl, C1-4alkylsulphonyl(C1-4)alkyl; (B) where q is an integer from 1 to 6 and R14 is halogeno; R7 is selected from C1-6alkyl, C1-8alkoxylcarbonyl, C2-6alkenyl, 1,3-benzodioxol-5-yl and aryl each optionally substituted by one or more substituents selected from C1-4alkoxy, C1-6alkyl, cyano, halogeno, and trifluoromethyl; R8 is aryl, heteroaryl, a bicyclic heteroaryl ring system linked to the nitrogen via a ring carbon or a 9 or 10 membered bicyclic ring system linked to the nitrogen via…
