Procedure

To a solution of 2-(4-(tert-butoxycarbonyl)-2-oxo-3-phenylpiperazin-1-yl)acetic acid (Example 101C, 0.334 g, 1 mmol) and 1-benzhydrylpiperazine (0.252 g, 1 mmol) in methylene chloride (10 mL) was added O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.38 g, 1 mmol) and diisopropylethylamine (0.8 mL). The reaction mixture was stirred at ambient temperature overnight. The reaction mixture was then diluted with methylene chloride, and then washed sequentially with 1 N HCl, water, 1 N NaOH, and water. The organic layer was dried over magnesium sulfate and concentrated in vacuo to yield the title compound. 1H NMR (300 MHz, CDCl3) δ ppm 7.44 (m, 6H), 7.30 (m, 7H), 7.19 (m, 2H), 5.74 (m, 1H), 4.51 (d, J=15.60 Hz, 1H), 4.23 (s, 1H), 4.12 (q, J=7.12 Hz, 1H), 3.96 (d, J=15.94 Hz, 1H), 3.59 (m, 3H), 2.38 (m, 5H), 1.44 (s, 9H); MS (ESI+) m/z 569 (M+H)+.
