Reaction Steps
To a mixture of ethyl (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-3-pyrrolidinyl]amino}-3-pyridyl)acrylate dihydrochloride (150 mg), [4-(bromomethyl)phenyl](phenyl)methanone (143 mg), and THF (3.5 mL) was added Et3N (0.168 mL). After stirring for 2 hours at room temperature, the reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over MgSO4, filtered, and evaporated in vacuo. The residue was purified by column chromatography on silica gel to give ethyl (2E)-3-{6-[[(3R)-1-(4-benzoylbenzyl)-3-pyrrolidinyl](tert-butoxycarbonyl)amino]-3-pyridyl}acrylate (149 mg)
