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 thiomorpholine 1,1-dioxide instead of 4-aminotetrahydropyran, to the title compound (94 mg, 84%) which was obtained as a light yellow solid after purification by chromatography (silica, 0 to 100% ethyl acetate in heptane). MS: m/e=449.1 [M+H]+.
