실험 절차

To a vial containing methyl 4-chlorobenzo[d][1,3]dioxole-5-carboxylate (395.8 mg, 1.8 mmol, 1 equiv.) in 3:1 THF:H2O (15 mL) was added LiOH.H2O (153.3 mg, 3.7 mmol, 2 equiv.). The vial was capped and the mixture was stirred at 70° C. for 2 h, diluted with water, acidified with 1M HCl to pH <3, and extracted with ethyl acetate. The combined organic layers was dried over anhydrous Na2SO4, filtered and the solvent was removed under vacuum to give a quantitative yield of 4-chlorobenzo[d][1,3]dioxole-5-carboxylic acid as a white solid.
