Versuchsvorschrift

A solution of acid 18 (0.24 g, 0.76 mmol) in THF (20 mL) was added with DEPC (0.15 mL, 1.3 mol eq) and the mixture was stirred at room temperature for several minutes. Then [2-pyrrolidin-1-yl-6-[4-(trifluoromethyl)phenyl]-4-pyridyl]methanamine 27A (0.27 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 (1×50 mL) and brine. After drying over Na2SO4, the separated organic phase was evaporated under reduced pressure and the residue was purified by flash chromatography (1:1 EtOAc:Petroleum ether) to afford a pale yellow solid (0.18 g) after crystallization from a mixture of ethyl ether/petroleum ether. Yield=38%, 1HNMR (DMSO, 200 MHz) δ 0.86 (t, 3H), 1.21 (m, 4H), 1.91 (m, 4H), 3.42 (m, 6H), 4.21 (d, 2H, J=6.2), 6.26 (s, 1H), 6.45 (s, 1H), 7.27 (d, 1H, J=4), 7.58 (d, 1H, J=3.8), 7.82 (d, 2H, J=7.8), 8.21 (d, 2H, J=8.1), 8.41 (t, 1H); [M+1] 613.11 (C27H28ClF3N4O3S2 requires 612.12).
