Reaction Steps

To a solution of 4-methyl-2-[2-(5-methyl-3-pyridin-2-yl-isoxazol-4-yl)-ethyl]-thiazole-5-carboxylic acid (100 mg, 0.3 mmol) in DMF (3 mL) was added 1,1′-carbonyldiimidazole (60 mg, 0.36 mmol). The resulting reaction mixture was stirred for 1 h at 60° C. and then treated with an ammonium hydroxide solution (455 μL, 3.0 mmol) and stirred for 2 h at room temperature. The reaction mixture was then evaporated. Purification by chromatography (silica, heptane:ethyl acetate 8:2 to 1:1) afforded the title compound (79 mg, 79%) as an off white solid. MS: m/e=329.1 [M+H]+.
