Reaction Steps

To a solution of 500 mg of (3RS,4RS)-3-(2,4-dichlorophenyl)-2-{(1SR,2SR)-2-[(methylsulfonyl)amino]cyclohexyl}-6-nitro-1-oxo-N-(pyridin-2-ylmethoxy)-1,2,3,4-tetrahydroisoquinoline-4-carboxamide in 10 ml of methanol-dioxane (1:1) was added 500 mg of Raney nickel, followed by stirring for 30 minutes under a hydrogen atmosphere. The catalyst was removed by filtration and the solvent was concentrated under reduced pressure to obtain 300 mg of (3RS,4RS)-6-amino-3-(2,4-dichlorophenyl)-2-{(1SR,2SR)-2-[(methylsulfonyl)amino]cyclohexyl}-1-oxo-N-(pyridin-2-ylmethoxy)-1,2,3,4-tetrahydroisoquinoline-4-carboxamide as a black solid.
