Ethanamine, 2,2,2-trifluoro- → 2-{(E)-2-[3-(5-Fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-yl]-vinyl}-thiazole-5-carboxylic acid (2,2,2-trifluoro-ethyl)-amide

Participants

Reaction Steps

As described for example 77c, 2-{(E)-2-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-yl]-vinyl}-thiazole-5-carboxylic acid (83 mg, 0.25 mmol) was converted, using 2,2,2-trifluoroethylamine instead of 4-aminotetrahydropyran, to the title compound (87 mg, 84%) which was obtained as a yellow solid after purification by chromatography (silica, 0 to 100% ethyl acetate in heptane). MS: m/e=413.1 [M+H]+.
