Reaction Steps

A mixture of 5-(4-fluorophenyl)-4-[4-(methylsulfonyl)phenyl]thiophene-2-carbonyl chloride (1.2 g) and sodium borohydride (0.21 g) in dioxane (15 ml) was stirred at ambient temperature for 2 hours. The mixture was diluted with ethyl acetate, washed with water, dilute hydrochloric acid, an aqueous solution of sodium bicarbonate, successively, dried and concentrated. The residue (1.2 g) was recrystallized from ethanol to give pale brown crystals of 5-(4-fluorophenyl)-4-[4-(methylsulfonyl)phenyl]thiophene-2-methanol (0.55 g).
