実験手順
A solution of acid 18 (463 mg, 1.5 mmol) in THF (30 mL) was added with DEPC (0.23 mL, 1.0 mol eq) and the mixture was stirred at room temperature for about 5 minutes. Then [2-[4-(cyclopropylmethyl)piperazin-1-yl]-6-[4-(trifluoromethyl)phenyl]-4-pyridyl]methanamine 27E (628 mg, 1.04 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 (40 mL) and washed with water (50 mL) and brine. The separated organic phase was dried over Na2SO4 and evaporated under reduced pressure and the residue was purified by flash chromatography (9:1 EtOAc:methanol) to afford a white solid (110 mg) after crystallization from diethyl ether. Yield=10%, 1HNMR (DMSO, 200 MHz) δ 1.15 (bm, 9H), 1.80 (bm, 4H), 2.35 (bm, 1H), 2.59 (bm, 4H), 3.37 (bm, 2H), 3.65 (bm, 4H), 4.45 (bd, 2H), 6.89 (s, 1H), 7.35 (m, 2H), 7.60 (d, 1H, J=3.4), 7.82 (d, 2H, J=8), 8.25 (bm, 3H). [M+1] 711.65 (C33H39ClF3N5O3S2 requires 710.27).
