Reaction Steps

To a solution of 5-chloro-2-neopentylaminophenyl 2-chlorophenyl thioketone (0.54 g) in ethanol (7 ml) was added ethyl hydrazinoacetate hydrochloride (0.11 g). The mixture was stirred for one day at 70° C. To the reaction mixture was added dichloromethane (50 ml), which was washed with water and, then, dried over anhydrous sodium sulfate. The solvent was distilled off. The residue was purified by means of a silica-gel column chromatography (hexane:acetic acid ethyl ester=15:1 v/v as an eluent) to give 0.16 g of an oily product.
