A suspension of 10 g of 10-methoxyiminostilbene in 250 ml dichloromethane was treated with 17.5 g of sodium cyanate and 24 g of mandelic acid and was heated to reflux for about 6-8 hrs. The reaction mixture was cooled to room temperature and the reaction mixture was washed with distilled water and aqueous sodium bicarbonate and further the organic layer was distilled off completely.
