To a stirred solution of 3-(6-benzyloxy-pyridin-3-yl)-2-{[4-(2-oxo-1,4-dihydro-2H-quinazolin-3-yl)-piperidine-1-carbonyl]-amino}-propionic acid methyl ester (59 mg, 0.11 mmol) in methanol (3 mL) was added a solution of lithium hydroxide monohydrate (9.1 mg, 2 equiv) in water (0.5 mL). The reaction was stirred 2 h at room temperature, cooled to 0° C., quenched by addition of 1N hydrochloric acid (0.15 mL), and concentrated. The crude product was used without purification. The crude acid was dissolved in methylene chloride (2 mL, 0° C.), and treated sequentially with 4-piperidino-piperidine (34 mg, 1.8 equiv), triethylamine (35 μL, 2.3 equiv.), and bis-2-oxo-3-oxazolidinyl)phoshinic chloride (34 mg, 1.2 equiv). The ice bath was removed and the reaction allowed to stir overnight. The reaction was concentrated and purified by Prep TLC to give 30.3 mg (41%). LC/MS: tR=1.49 min, 680.29 (MH)+.
