wherein
R, and R4 are independently phenyl optionally substituted by one, two or three of halogen, trifluoromethyl, C, 4 alkoxy, C1-4 alkyl, cyano, hydroxy, nitro, NR5R6 or O2SNR5R6 wherein Rs and R6 are independently hydrogen or C1-6 alkyl or together are C3-6 polymethylene, or disubstituted at adjacent carbon atoms by C1-2 alkylenedioxy and optionally further substituted by one of the above groups;
R2 is selected from (CH2)2 CN where z is 0 or an integer from 1 to 4, C1-2alkyl,C3-7cycloalkyl,C3-7cycloalkylC1-4 alkyl, phenyl C1-4 alkyl, pyridyl, pyridyl C1-4 alkyl, COR7, COCH2COR7, S02R7, C02R7, CONHR7 and CSNHR7, where R7 is selected from C3-12 alkyl, C3-7 cycloalkyl, C3-7 cycloalkyl C1-4 alkyl, phenyl and phenyl C1-4 alkyl, any alkyl moiety in R7 optionally substituted by hydroxy or C1-4 alkanoyloxy, any pyridyl or phenyl moiety in R2 optionally substituted as defined for R' and R4 and any cycloalkyl moiety in R2 optionally substituted by one or two C1-4 alkyl groups;
R3 is hydrogen or C1-4 alkyl;
A represents C2.5 alkylene; and
B represents C1-4 alkylene.
