Procedure

1-{7-Chloro-1-[2-methyl-4-(2-methyl-benzoylamino)-benzoyl]-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yloxycarbonylmethyl}-piperazine dihydrochloride (400 mg, 0.62 mmol), formalin (0.15 ml, 1.9 mmol), sodium acetate (61 mg, 0.74 mmol), and sodium cyanotrihydroborate (119 mg, 1.9 mmol) were added to methanol (5 ml), and the mixture was stirred at room temperature for 1 hour. Water and aqueous sodium hydroxide solution were added to the reaction mixture, and the precipitates were collected by filtration, washed with water, and then dried. The obtained solid was dissolved in ethyl acetate, and a 4N hydrogen chloride ethyl acetate solution (0.5 ml) was added thereto. The precipitates were then collected by filtration, washed with ethyl acetate and dried to obtain 240 mg of 1-{7-chloro-1-[2-methyl-4-(2-methyl-benzoylamino)-benzoyl]-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yloxycarbonylmethyl}-4-methyl-piperazine dihydrochloride as white powder.
