Diisopropylethylamine → HCID 86675140, compound

Participants

Reaction Steps

To a stirred solution of 3,3,3-trifluoropropanoic acid (0.02 g, 0.16 mmol) in DCM (10.0 mL), (E)-2-bromo-N-(piperidin-4-yl)-4-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-enyl)benzamide (0.1 g, 0.16 mmol), PYBOP (0.09 g, 0.17 mmol), and DIPEA (0.06 g, 0.48 mmol) were added at RT. The reaction mixture was stirred at RT for 5 h. The reaction mixture was diluted with DCM. The combined DCM layer was washed with 3N HCl and saturated NaHCO3 solution, the separated DCM layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford crude compound. The crude compound was purified by column chromatography (SiO2, 100-200 mesh; eluting with 2% methanol in DCM) to afford the title compound as an off white gummy material (0.035 g, 29.%).
