Barium hydroxide, octahydrate → 3-({[(3R)-1-{3-[1-(tert-butoxycarbonyl)piperidin-4-yl]propanoyl}piperidin-3-yl]carbonyl}amino)-3-{5-[3-(2-fluoroethoxy)phenyl]pyridin-3-yl}propanoic acid

Participants

Reaction Steps

95 mg (0.14 mmol) Tert-butyl 4-{3-[(3R)-3-{[1-{5-[3-(2-fluoroethoxy)phenyl]pyridin-3-yl}-3-methoxy-3-oxopropyl]carbamoyl}piperidin-1-yl]-3-oxopropyl}piperidine-1-carboxylate were dissolved in 17 ml methanol. 448 mg (1.42 mmol) barium hydroxide octahydrate were added. The mixture was stirred at room temperature for 20 hours and then concentrated to give 3-({[(3R)-1-{3-[1-(tert-butoxycarbonyl)piperidin-4-yl]propanoyl}piperidin-3-yl]carbonyl}amino)-3-{5-[3-(2-fluoroethoxy)phenyl]pyridin-3-yl}propanoic acid.
