Reaction Steps

to a solution of methyl [3-(5-{1-[(tert-butoxycarbonyl)(cyclopropyl)amino]ethyl}-2-vinylpyridin-3-yl)propyl]carbamate (280 mg) in methanol (10 mL) was added 10% palladium on carbon (140 mg), and the mixture was stirred under hydrogen for 2 hours. An insoluble was filtered off, and then the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: chloroform→chloroform/methanol=4/1) to give methyl [3-(5-{1-[(tert-butoxycarbonyl)(cyclopropyl)amino]-ethyl}-2-ethylpyridin-3-yl)propyl]carbamate [REx(113-7)] (210 mg) as a pale yellow oil.
