反応手順
N,N-Dimethylformamide (few drops), followed by oxalyl chloride (9.5 mL, 106 mmol) were added dropwise to a cooled (10° C.) solution of (3-methyl-isoxazol-5-yl)-acetic acid (5 g, 35.4 mmol) in dichloromethane (50 mL), and the solution was allowed to warm to room temperature. The reaction was stirred for a further 3 hours, then concentrated under reduced pressure. The residue was azeotroped with toluene to afford the title compound.
