実験手順

To a solution of compound 2 (2.0 g, 14.1 mmol), 1-Benzyl-4-trifluoromethyl-pyrrolidine-3-carboxylic acid (4.06 g, 14.9 mmol) and DIEA (10 mL, 42.5 mmol) in DMF (30 mL) was added HATU (8.1 g, 21.2 mmol). The resulting reaction mixture was stirred at r.t. overnight. The reaction was monitored by LC-MS. The reaction was quenched with water (100 mL) when it was complete. The aqueous solution was extracted with EtOAc (80 mL×3). The combined organic phase was washed with brine and concentrated to afford the crude product. The residue was purified by silica gel column (eluted with PE/EA=5:1 to 1:2) to afford compound 13 (4.8 g, 85.6% yield) as white oil. LC-MS: m/z 397 [M+1]+. 1H NMR (400 MHz, CDCl3): δ 8.00 (br. s, 1H), 7.70 (s, 1H), 7.65 (s, 1H), 7.34˜7.28 (m, 5H), 3.81 (s, 3H), 3.78˜3.72 (m, 2H), 3.41˜3.38 (m, 1H), 3.30˜3.24 (m, 2H), 3.14˜3.12 (m, 1H), 2.71˜2.67 (m, 1H), 2.58˜2.53 (m, 1H).
