Versuchsvorschrift

To a stirred solution of 5-bromo-2-formylbenzonitrile (200 mg, 0.95 mmol) and morpholine (248 mg, 2.85 mmol) in dichloroethane (10 mL), acetic acid (342 mg, 5.7 mmol) was added and reaction stirred at room temperature for 30 minutes. Then sodium triacetoxyborohydride (604 mg, 2.85 mmol) was added to the reaction mixture at 0° C., allowed to attain room temperature and stirring continued for overnight. On completion, reaction mixture was diluted with dichloromethane, washed with water, saturated aqueous sodium bicarbonate solution and dried over sodium sulphate. Removal of the solvent under reduced pressure followed by column chromatographic purification afforded the desired compound (150 mg, 56%).
