Procedure

To a solution of 600 mg of methyl 5-{[({[(3RS,4RS)-3-(2,4-dichlorophenyl)-2-{(1SR,2SR)-2-[(methylsulfonyl)amino]cyclohexyl}-1-oxo-1,2,3,4-tetrahydroisoquinolin-4-yl]carbonyl}amino)oxy]methyl}thiophene-3-carboxylate in 40 mL of THF was added 45 mg of lithium aluminum hydride at −78° C. The solution was warmed to 0° C., followed by stirring for 3 hours. Sodium sulfate decahydrate was added thereto, followed by stirring for 1 hour. After removing sodium sulfate by filtration, the organic layer was dried by adding anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent:chloroform-methanol) to obtain 162 mg of (3RS,4RS)-3-(2,4-dichlorophenyl)-N-{[4-(hydroxymethyl)-2-thienyl]methoxy}-2-{(1SR,2SR)-2-[(methylsulfonyl)amino]cyclohexyl}-1-oxo-1,2,3,4-tetrahydroisoquinoline-4-carboxamide as a white solid.
