Versuchsvorschrift

A solution of acid 4B (0.40 g, 1.46 mmol) in THF (20 mL) was added with DEPC (0.28 mL, 1.3 mol eq) and the mixture was stirred at room temperature several minutes. Then [2-morpholino-6-[4-(trifluoromethyl)phenyl]-4-pyridyl]methanamine 27B (530 mg, 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, water was added to the residue that is extracted with EtOAc (3×30 mL) and washed with brine (1×40 mL). The separated organic phase was dried over Na2SO4, evaporated to dryness and the residue was purified by flash chromatography (6/4 EtOAc/Petroleum ether) to afford a white solid (95 mg) after crystallization from ethyl ether. Yield=12%. 1HNMR (DMSO, 200 MHz) δ 1.087 (t, 3H, J=7.8), 3.39 (q, 2H, J=7.6), 3.55 (m, 4H), 3.71 (m, 4H), 4.42 (d, 2H, J=6.2), 5.13 (s, 1H), 6.12 (s, 1H), 6.85 (s, 1H), 7.35 (s, 1H), 7.47 (t, 2H, J=8), 7.83-7.90 (m, 4H), 8.26 (d, 2H, J=8), 8.80 (bt, 1H). [M+1] 592.33 (C28H28F4N4O4S requires 592.60).
