Reaction Steps

Sodium borohydride (0.22 g) was added portionwise to a solution of 4'-acetyl-2'-(2,4-dichlorophenylthio)methanesulfonanilide (1.5 g) in tetrahydrofuran (20 ml) and methanol (10 ml) at room temperature. The mixture was stirred for 9 hours, treated with acetic acid, and concentrated under reduced pressure. The residue was dissolved in ethyl acetate, washed with an aqueous solution of sodium bicarbonate, and dried. The solution was evaporated to dryness and the residue was recrystallized from a mixture of ethanol and water to give colorless needles of 2'-(2,4-dichlorophenylthio)-4'-(1-hydroxyethyl)methanesulfonanilide (1.3 g).
