Procedure

A solution of 4-bromophenylhydrazine hydrochloride (2.24 g) and 1,3-cyclohexanedione (1.23 g) in water (60 ml) was stirred at room temperature for 1 h, giving a precipitate. The solid title compound was filtered off and dried (1.63 g). t.l.c (D), Rf 0.35 On cooling a second crop was obtained (0.395 g)
