Procedure

To the compound (6.61 g, 17.67 mmol) obtained in step B was added 1N hydrochloric acid, and generated benzaldehyde was evaporated by azeotropic distillation in a flask mounted with Dean-Stark water removing apparatus (Dean-Stark trap) for 6 hr. The reaction mixture was cooled, washed with diethyl ether, and the aqueous layer was alkalified with potassium carbonate. The layer was extracted twice with ethyl acetate (150 ml), and the organic layer was combined. The mixture was washed with saturated brine, and dried over anhydrous magnesium sulfate. The insoluble material was filtered off, and the solvent was concentrated under reduced pressure to give the title compound (4.85 g, yield 96%) as a yellow oil.
