Reaction Steps

To 2-(2-oxo-3,3-diphenylpyrrolidin-1-yl)acetic acid (Example 1C, 0.031 g, 0.105 mmol) and 2-(1H-benzo[d][1,2,3]triazol-1-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (0.044 g, 0.115 mmol) in dichloromethane (0.5 mL) was added diisopropylethylamine (0.027 mL, 0.157 mmol) followed by phenylmethanamine (0.014 mL, 0.126 mmol). After stirring overnight, the reaction was loaded onto a silica gel column (Analogix® SF15-12, Burlington, Wis.), and the product was eluted with a gradient of 0.4% to 5.25% methanol/dichloromethane over 20 minutes with a flow rate of 30 mL/minute. The product residue was dissolved in dichloromethane/diethyl ether followed by the addition of hexanes which upon concentration gave the title compound. 1H NMR (300 MHz, CDCl3) δ ppm 7.11-7.34 (m, 15H), 6.23 (t, J=5.8 Hz, 1H), 4.32 (d, J=5.8 Hz, 2H), 4.06 (s, 2H), 3.50 (t, J=6.5 Hz, 2H), 2.80 (t, J=6.5 Hz, 2H); MS (ESI−) m/z 383 (M−H)−.
