Triethylamine → 2-Chloro-N-(3-[(1E)-3-oxo-3-({2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethyl}amino)prop-1-en-1-yl]phenyl)nicotinamide

Participants

Reaction Steps

100 mg (0.25 mmol) of (2E)-3-(3-aminophenyl)-N-{2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]-ethyl}acrylamide from Example 3, Stage 2 and 33.8 mg (0.33 mmol) of triethylamine were initially charged in 1 ml of trichloromethane, and a solution of 49.8 mg (0.33 mmol) of 2-chloronicotinoyl chloride in 1 ml of trichloromethane was added. The reaction solution was stirred at room temperature for 18 hours, then diluted with dichloromethane, washed three times with water and dried over sodium sulphate. The solvent was distilled off under reduced pressure and the residue purified by preparative HPLC (solvent=water (A)+acetonitrile (B), gradient=40 min, from 10% B to 100% B, flow=18 ml/min).
