Reaction Steps

To a solution of methyl (R)-(-)-4-[5-[2-[N-tert-butoxycarbonyl-2-[2-(2,2,2-trifluoroethoxy)phenoxy]ethylamino]propyl]-7-carbamoylindolin-1-yl]butyrate (187 mg) in a saturated ammonia in methanol (2 ml) was added sodium cyanide (2 mg), and the mixture was stirred in a sealed tube at 50° C. for 71 hours. The reaction mixture was concentrated under reduced pressure, and the residue was purified by medium pressure liquid column chromatography on silica gel using a mixture of methylene chloride, diethyl ether and methanol (5/5/1) as eluent to give 145 mg of (R)-(-)-4-[5-[2-[N-tert-butoxycarbonyl-2-[2-(2,2,2-trifluoroethoxy)phenoxy]ethylamino]propyl]-7-carbamoylindolin-1-yl]butyramide as an oil.
