실험 절차

A solution of acid 4C (0.50 g, 1.8 mmol) in THF (30 mL) was added with DEPC (0.35 mL, 1.3 mol eq) and the mixture stirred at room temperature several minutes. Then [2-[4-(trifluoromethoxy)phenyl]-4-pyridyl]methanamine 21B (0.53 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 and washed with water and brine. The separated organic phase was dried over an. Na2SO4 and evaporated under reduced pressure. The residue was purified by flash chromatography (7:3 EtOAc:Petroleum ether) to afford a pale yellow viscous oil (0.17 g). Yield=18%, 1HNMR (DMSO, 200 MHz) δ 2.98 (s, 3H), 4.22 (d, 2H), 5.08 (s, 1H), 5.85 (s, 1H), 7.4 (m, 3H), 7.65 (dd, 4H, J=8), 7.95 (s, 1H), 8.2 (d, 2H), 8.58 (d, 1H), 8.95 (t, 1H); [M+1] 525.93 (C23H19ClF3N3O4S requires 525.07).
