Reaction Steps

To a solution of 6-[3-(3,4-difluoro-phenyl)-5-hydroxymethyl-isoxazol-4-ylmethoxy]-nicotinic acid (100 mg, 0.28 mmol) in THF (3 mL) were added 1-hydroxybenzotriazole hydrate (43.1 mg, 0.28 mmol), N-ethyldiisopropylamine (120 μL, 0.69 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (54.0 mg, 0.28 mmol) and 1-methyl-1H-pyrazol-4-ylamine (26.8 mg, 0.28 mmol). The reaction mixture was stirred overnight at room temperature. Chromatography (silica, ethyl acetate:heptane=2:1 to 9) afforded the title compound (3.5 mg, 3%) as a colourless oil. MS: m/e=442.2 [M+H]+.
