Procedure

To a stirred solution of (E)-5-(3-(3,5-dichloro-4-fluorophenyl)-4,4,4-trifluorobut-1-enyl)indoline-1-amine (0.1 g, 0.247 mmol) in CH2Cl2 (10.0 ml) was added 3,3,3-trifluoropropanoic acid (0.038 g, 0.297 mmol), PyBOP (0.192 g, 0.370 mmol) and DIPEA (0.047 g, 0.370 mmol) and the reaction was stirred at ambient temperature for 18 h. The reaction mixture was diluted with CH2Cl2, and the separated CH2Cl2 layer dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford the crude compound. The crude compound was purified by column chromatography (SiO2, 100-200 mesh; 20-25% EtOAc/petroleum ether) to afford the title compound as a light brown gummy material (0.12 g, 33%): 1H NMR (400 MHz, CDCl3) δ 7.32, (d, J=6.0 Hz, 2H) 7.28 (m, 1H), 7.20 (d, J=8.0, 1H), 7.14 (d, J=8.8, 1H), 6.70 (d, J=8.0 Hz, 1H), 6.60 (m, 2H), 4.15 (m, 1H), 3.85 (m, 1H), 3.65 (m, 1H), 3.46 (m, 2H), 3.19 (m, 2H); ESIMS m/z 514.86 ([M+H]+); IR (thin film) 3428, 1112, 857 cm−1.
