Procedure
7. The crude cyanomethylbenzofuran, compound 6, was stirred for 6 hours in boiling water (1,000 ml) containing sodium hydroxide (80 g), cooled to 25° C., then washed with methylene chloride (250 ml, then 2×100 ml). The pH was brought to 2.0 with 6 N HCl. The precipitate was extracted with methylene chloride (200 ml, then 100 ml, then 50 ml), dried over magnesium sulfate and the solvent evaporated. The yield was approximately 72 g.
