Procedure

To a solution of 2-{2-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-yl]-ethyl}-4-methyl-thiazole-5-carboxylic acid (69 mg, 0.20 mmol) in DMF (1.2 mL) were added 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (71 mg, 0.22 mmol), N,N-diisopropyl ethyl amine (171 μL, 1.00 mmol) and 4-aminotetrahydropyran (22 mg, 0.22 mmol). The resulting reaction mixture was stirred for 1 h and then evaporated. Purification by chromatography (silica, heptane:ethyl acetate 4:1 to 0:1) afforded the title compound (81 mg, 94%) as an off white solid. MS: m/e=431.2 [M+H]+.
