Procedure

Following the procedure as described in Example 24, except using suspension of (R)-2-(((9H-fluoren-9-yl)methoxy)carbonylamino)-3-(tert-butoxycarbonylamino)propanoic acid (500 mg, 1.172 mmol), L-leucine allyl ester p-toluenesulfonate salt (411 mg, 1.196 mmol), 1-hydroxy-7-azabenzotriazole (80 mg, 0.586 mmol), CH2Cl2 (40 mL), N-methylmorpholine (0.258 mL, 2.345 mmol), and EDC (247 ing, 1.290 mmol), 137 mg (20.16%) of the title compound is isolated as a white solid. Purification is done by BIOTAGE® Silica gel chromatography on a 90 g Thompson Single Step silica cartridge using a linear gradient from 100% Hexanes to 100% (1:1 EtOAc/Hexanes) over 12 column volumes. LC/MS (Condition A): ret. T=4.50 min, (2M+Na) 1181.97.
