Procedure

To a solution of 128 mg of (3RS,4RS)—N-(cyanomethoxy)-3-(2,4-dichlorophenyl)-2-{(1SR,2SR)-2-[(mesyl)amino]cyclohexyl}-1-oxo-1,2,3,4-tetrahydroisoquinoline-4-carboxamide in 1.92 ml of methanol was added 0.018 ml of a hydroxylamine solution at room temperature, followed by warming to 40° C. and stirring overnight. The reaction solution was cooled to room temperature and the precipitated crystal was then collected by filtration to obtain 26 mg of (3RS,4RS)—N-[2-amino-2-(hydroxyimino)ethoxy]-3-(2,4-dichlorophenyl)-2-{(1SR,2SR)-2-[(mesyl)amino]cyclohexyl}-1-oxo-1,2,3,4-tetrahydroisoquinoline-4-carboxamide as a white crystal.
