Procedure

A solution of acid 15A (0.30 g, 1.8 mmol) in THF (20 mL) was added with DEPC (0.21 mL, 1.3 mol eq) and the mixture was stirred at room temperature for 10 minutes. Then [3-[4-(trifluoromethoxy)phenyl]phenyl]methanamine 23B (0.308 g, 1.1 mol eq) and a catalytic amount of TEA were added, then the reaction mixture was stirred at room temperature overnight. The solvent was removed under reduced pressure, the residue was suspended in EtOAc (45 mL) and washed with water (50 mL) and brine. The separated organic phase was dried over an. Na2SO4 and evaporated under reduced pressure. The residue was purified by flash chromatography (1:1 EtOAc:Petroleum ether) to afford a white solid (0.15 g). Yield=28%, 1HNMR (DMSO, 200 MHz) δ 1.08 (m, 2H), 1.20 (t, 3H, J=8), 1.38 (bs, 2H), 3.42 (q, 2H), 4.38 (d, 2H, J=5.6), 7.27 (d, 1H, J=4), 7.46-7.39 (m, 6H), 7.55 (d, 1H), 7.59 (s, 1H), 7.78 (m, 2H), 7.87 (m, 2H), 8.08 (t, 1H).
