ABSTRACT:
The present invention relates to compounds of formula I:wherein one of R1and R4is selected from the group consisting of H, and optionally substituted C1-6alkyl, C3-7cycloalkyl, C3-7cycloalkyl-C1-4alkyl, and phenyl-C1-4alkyl; and the other of R1and R4is an optionally substituted C9-14aryl group; R2and R3are either:(i) independently selected from H, R, R′, SO2R, C(═O)R, (CH2)nNR5R6, where n is from 1 to 4 and R5and R6are independently selected from H and R, where R is optionally substituted C1-4alkyl, and R′ is optionally substituted phenyl-C1-4alkyl, or(ii) together with the nitrogen atom to which they are attached, form an optionally substituted C5-7heterocyclic group; and their use as pharmaceuticals, in particular for treating conditions alleviated by the antagonism of a 5-HT2Breceptor.
