PROCEDURE

实验过程

A suspension of 15.1 g. (0.136 mol.) of aminomethanesulfonic acid and 14.2 g. (0.145 mol.) of anhydrous potassium acetate in 48 ml. of acetic acid is refluxed for ten minutes. Phthalic anhydride (21.4 g., 0.145 mol.) is then added and the resulting mixture is refluxed for 2.5 hours. The product is collected by filtration and washed with acetic acid and ethanol to give phthalimidomethanesulfonic acid potassium salt.
