Procedure
73 mg (0.11 mmol) tert-butyl 4-(3-{(3R)-3-[(1-{5-[2-(2-fluoroethoxy)phenyl]pyridin-3-yl}-3-methoxy-3-oxopropyl)carbamoyl]piperidin-1-yl}-3-oxopropyl)piperidine-1-carboxylate were dissolved in 13 ml methanol. 344 mg (1.09 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-[2-(2-fluoroethoxy)phenyl]pyridin-3-yl}propanoic acid.
