methyl (2E,4S)-4-({[8-(cyclohexylmethoxy)-2-methylimidazo[1,2-a]pyridin-3-yl]carbonyl}amino)-4-phenylbuta-2-enoate → methyl (4S)-4-({[8-(cyclohexylmethoxy)-2-methylimidazo[1,2-a]pyridin-3-yl]carbonyl}amino)-4-phenylbutanoate

Participants

Reaction Steps

To a solution of 185 mg of methyl (2E,4S)-4-({[8-(cyclohexylmethoxy)-2-methylimidazo[1,2-a]pyridin-3-yl]carbonyl}amino)-4-phenylbuta-2-enoate in 3.7 ml of ethyl acetate was added 20 mg of 10% palladium-carbon, followed by stirring for 8 hours under a hydrogen atmosphere. The reaction mixture was filtered over Celite and the solvent was evaporated under reduced pressure to obtain 165 mg of methyl (4S)-4-({[8-(cyclohexylmethoxy)-2-methylimidazo[1,2-a]pyridin-3-yl]carbonyl}amino)-4-phenylbutanoate.
