Procedure

To a mixed liquid of 200 mg of (3RS,4RS)-2-[(1SR,2SR)-2-aminocyclohexyl]-Nenzyloxy)-3-(2,4-dichlorophenyl)-1-oxo-1,2,3,4-tetrahydroisoquinoline-4-carboxamide and 40 ml of dimethoxyethane was added 357 mg of sulfamide, followed by stirring at 80° C. for 2 days. The reaction solution was concentrated, added with chloroform, and then washed with water. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was then evaporated. The residue was purified by silica gel column chromatography (eluent: chloroform-methanol), crystallized from ethyl acetate, and collected by filtration to obtain 62 mg of (3RS,4RS)-2-{(1SR,2SR)-2-[(aminosulfonyl)amino]cyclohexyl}-N-(benzyloxy)-3-(2,4-dichlorophenyl)-1-oxo-1,2,3,4-tetrahydroisoquinoline-4-carboxamide as a white crystal.
