실험 절차

To a solution of 2-amino-4-hydroxymethyl-benzoic acid methyl ester (7.8 g, 43 mmol) in dioxane (150 mL) was added acetyl chloride (3.04 mL, 1 equiv) and the resulting mixture was stirred at 90° C. for 18 h. The solution was concentrated in vacuo and the resulting oil was sonicated in DCM/hexanes (2/8). The solid was filtered off, washed with hexanes and dried to afford a white solid (7.03 g, 73.2%) (ES-MS: m/z 224.2 [M+H]+, rt 3.75 min).
