Reaction Steps

A solution of (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-[4-methyl-3-[[(2,5-dioxopyrrolidino)methyl]amino]benzyl]-4-[2-[(2S)-2-(methoxymethyl)morpholino]ethyl]piperazine (0.14 g) in dimethylsulfoxide (0.42 ml) was added sodium borohydride (10 mg) and the whole was stirred at 80° C. for 15 hours. After cooling, water and ethyl acetate were added to the mixture. The organic layer was separated, washed with brine, dried over sodium sulfate and evaporated in vacuo. The residue was purified by column chromatography on silica gel with a mixture of methylene chloride and methanol (30:1 to 10:1) as eluent to give (2R)-1-[3,5-bis(trifluoromethyl)-benzoyl]-2-[4-methyl-3-(methylamino)benzyl]-4-[2-[(2S)-2-(methoxymethyl)morpholino]ethyl]piperazine (37 mg) and (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-[4-methyl-3-[[(5-hydroxy-2-oxopyrrolidino)methyl]amino]benzyl]-4-[2-[(2S)-2-(methoxymethyl)morpholino]ethyl]piperazine (45 mg), respectively. Each compound was converted to its trihydrochloride in a conventional manner.
