Procedure

16.4 ml of bromine dissolved in 35 ml of acetic acid are poured at 18° C. onto 53.6 g of nitrile obtained in Stage C dissolved in 179 ml of acetic acid. The mixture is stirred for 1 hour, then left overnight at room temperature and hydrolysed with 31.5 g of potassium acetate dissolved in 150 ml of water and 196.5 g of ice. The mixture is extracted with diethyl ether and the ethereal phase is washed several times with water and dried.
