Procedure
5-Nitrobenzofuran-2-carboxylic acid (10 g) was dissolved in methanol (200 mL) and chloroform (100 mL), and the mixture was cooled to 0° C. Under stirring conditions was bubbled HCl gas until the solution was saturated. The reaction mixture was stirred at room temperature overnight, and white solid was formed. The precipitate was collected by filtration to afford 9.5 g of the title compound.
