Participants

Reaction Steps

30 mg (1.2 eq, 0.28 mmol) of isobutyryl chloride were dissolved in 1 ml of dichloromethane. To this were added 113 mg (1.0 eq, 0.24 mmol) of the hydrochloride of (2E)-3-[4-(aminomethyl)-3-(trifluoromethyl)phenyl]-N-(2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethyl)acrylamide from Stage 5 and 93 mg (3 eq) of Hünig's base. The mixture was stirred at room temperature for 16 h then concentrated. The crude product was purified by means of preparative HPLC (Phenomenex Gemini C18 5 μm; 125A; Aqua 50×21.2 mm; gradient: 0-1.5 min 78% water, 20% acetonitrile, 1.5-10.0 min linear gradient to 18% water, 80% acetonitrile, 10.0-14.00 min 18% water, 20% acetonitrile; modifier: 10% NH4HCO3 added at 2 ml/min). This gives 57 mg (44%) of (2E)-3-{4-[(isobutyrylamino)methyl]-3-(trifluoroethyl)phenyl}-N-{2,2,2-trifluoro-1-[3-(trifluoro-methyl)phenyl]ethyl}acrylamide.
