실험 절차

To a solution of 2-[2-(3-butyl-5-methyl-isoxazol-4-yl)-ethyl]-4-methyl-thiazole-5-carboxylic acid (80 mg, 0.26 mmol) in DMF (4 mL) were added 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (92 mg, 0.29 mmol), N,N-diisopropyl ethyl amine (168 mg, 1.3 mmol) and 1-amino-2-methyl-propan-2-ol (25 mg, 0.29 mmol). The resulting reaction mixture was stirred for 15 h and then evaporated. Purification by chromatography (silica, 0 to 10% methanol in dichloromethane) afforded the title compound (55 mg, 56%) as a colourless oil MS: m/e=380.4 [M+H]+.
