Procedure

70 g of sodium hydrosulphite are added portionwise and with stirring to a solution of 32 g of 6-chloro-3-(β-hydroxyethoxy)-4-nitrophenol phenate and 75 ml of 10 N NaOH in 250 ml of water, the temperature being maintained in the region of 60°-65° C. After the mixture is cooled, the product is precipitated by neutralizing the reaction medium with acetic acid. The hydrochloride is obtained by dissolution in hydrochloric acid in the heated state and precipitation on cooling.
