Triethylamine → 3-(6-Chloro-pyridin-3-yl)-N-(3-ethynyl-5-fluoro-4-methane sulfonylamino-benzyl)-acrylamide

Participants

Reaction Steps

N-(4-Aminomethyl-2-ethynyl-6-fluoro-phenyl)-methanesulfonamide HCl salt (78.3 mg, 0.272 mmol) was suspended in THF and treated with triethylamine (30 mg, 0.299 mmol) and then the resulting mixture was stirred for 10 mins. 3-(6-chloro-pyridin-3-yl)-acrylic acid (50 mg, 0.272 mmol) was added to the reaction mixture followed by DMTMM (82 mg, 0.299 mmol) after 10 mins. The resulting mixture was stirred overnight at ambient temperature and then diluted with EtOAc. The resulting solution was washed successively with water, sat'd NaHCO3 (×2), brine, and then dried over anhyd. Na2SO4, filtered and concentrated under reduced pressure. The crude residue was recrystallized (CH2Cl) to yield the title compound (26 mg, 23%).
