To a stirred solution of 2-[(E)-2-(5-methyl-3-phenyl-isoxazol-4-yl)-vinyl]-thiazole-5-carboxylic acid ethyl ester (30 mg, 0.09 mmol) in toluene (0.5 mL) was added rac-2-amino-1-propanol (9 mg, 0.12 mmol) and TBD (4 mg, 0.03 mmol). After 15 h, the reaction mixture was concentrated in vacuo then purified by chromatography (silica, 0 to 3% methanol in dichloromethane) to give the title compound (26 mg, 80%) as a white solid. MS: m/e=370.0 [M+H]+.
