실험 절차

Ammonia was passed for 1 hour at 10-15° C. into a solution of 10 g (55.56 mmol) of 5-chloromethylisoxazole-3-carboxylic acid chloride in 100 ml of methylene chloride and stirring was subsequently continued at room temperature for 1 hour. After the solution had cooled to 0° C., the precipitate was filtered off with suction and washed with a little cold methylene chloride, and the residue was extracted twice by stirring with water to remove the ammonium salts. Drying in vacuo resulted in 6.58 g of pure product as a pale powder (74% of theory)
