Reaction Steps

Borane methylsulfide (1.6 ml) was added dropwise to a cold solution (8–10° C.) of crude benzo[1,2,5]thiadiazol-5-yl-acetic acid (b) (2.8 g, 14 mmol) in tetrahydrofuran (20 ml). Stirring was continued for 1.25 hours while maintaining the temperature below 30° C. The mixture was cooled to 10° C. then methanol was added (1.4 ml) and the mixture was left 15 hours in the refrigerator. The mixture was diluted with ethyl acetate, washed with water then with a saturated aqueous solution of sodium hydrogencarbonate and again with water. The organic phase was separated, dried over magnesium sulfate and evaporated. The residue was triturated in pentane, collected by filtration and dried to give crude 2-benzo[1,2,5]thiadiazol-5-yl-ethanol (1.8 g, 71%).
