Procedure

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 cyclopropylamine instead of 4-aminotetrahydropyran, to the title compound (40 mg, 43%) which was obtained as a light yellow solid after recrystallization from heptane/ethyl acetate. MS: m/e=371.1 [M+H]+.
