Procedure

Prepared using General Procedure 7. To a stirring solution of (S)-2-(((benzyloxy)carbonyl)amino)-3-(4-(5-(4-(heptyloxy)phenyl)pyrimidin-2-yl)phenyl)propanoic acid INT-22 (2082 mg, 2.75 mmol), methyl (S)-pyrrolidine-3-carboxlate HCl (545 mg, 3.30 mmol), and DIEA (1523 μl, 8.25 mmol) in DMF (6 mL) cooled to 0° C. was slowly added a solution of HATU (1254 mg, 3.30 mmol) in DMF (5 mL) in a drop-wise fashion The reaction mixture was allowed to warm slowly and stirring continued for 4 h. The reaction mixture was poured onto ice-water and the solid was filtered. The solid was dissolved in EA (50 mL), dried over MgSO4, evaporated and purified by chromatography (EA/hexane) to provide 932 mg (52%) of methyl (S)-1-((S)-2-(((benzyloxy)carbonyl)amino)-3-(4-(5-(4-(heptyloxy)phenyl)pyrimidin-2-yl)phenyl)propanoyl)pyrrolidine-3-carboxylate. LCMS-ESI (m/z) calculated for C40H46N4O6: 678.3. found 679.3 [M+H]+, tR=4.50 min (Method 16).
