Benzyl bromide (0.15M) was added to a stirred mixture of 1-phenylaminonaphthalene (0.1M) and KOH (0.15M) in N-methyl pyrrolidone (70 cm3) at 120° C. After 2 hours further stirring the mixture was poured in to water, the precipitate filtered off, washed and re-crystallised from methanol to give 20 g (65% yield) of a white solid mp 120°-123° C.
