Triethylamine → 5-bromo-N-[1-(trifluoromethyl)cyclopropyl]pyridine-2-carboxamide

Participants

Reaction Steps

A mixture of 5-bromopyridine-2-carboxylic acid (150 mg, 0.74 mmol), 1-(trifluoromethyl)cyclopropanamine (93 mg, 0.74 mmol) (Oakwood, Cat. #: 038175), benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (345 mg, 0.780 mmol) and triethylamine (310 μL, 2.2 mmol) in methylene chloride (1 mL) was stirred at room temperature for 3 h. The mixture was concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column with methanol in dichloromethylene (0-5%) to afford the desired product (124 mg). LCMS (M+H)+: m/z=309.0.
