ABSTRACT:
A process for preparing an intermediate compound of formula (II)where n is an integer of from 3 to 14;R1is haloC1-10alkyl, C1-10alkyl, C2-10alkenyl, C2-10cycloalkyl, carboxyC1-10alkyl, C1-10alkoxycarbonylC1-10alkyl, aryl (such as phenyl), aryl(C1-10)alkyl (such as phenyl(C1-10)alkyl) or di(C1-6alkyl)amino;and R2is a halo group; the process comprising halogenation of a compound of formula (III)where n and R1are as defined above.Novel compounds are also described and claimed.
