실험 절차

Methyl 7-chlorobenzo[b]thiophene-2-carboxylate (3 g, 13 mmol) was dissolved is ethanol (15 mL) and treated 5 N sodium hydroxide (5 mL). The reaction was heated at reflux overnight. The volatiles were removed in vacuo and the aqueous residue was acidified to pH 2 using 5 N HCl. The resulting white solid was filtered off, washed well with water and dried in a vacuum oven at 60° C. Yield=2.6 g. MS (M−H)− 210.
