Sodium borohydride → HCID 16756658, compound

Participants

Reaction Steps

To a solution of 3-(4-trifluoromethoxyphenyl)-[1,2,4]thiadiazole-5-carboxylic acid ethyl ester (0.11 g, 0.35 mmol) in MeOH (10 ml) was added sodium borohydride (0.022 g, 0.59 mmol) portion wise. The resulting reaction mixture was stirred at room temperature for 2 h. After the completion of the reaction (TLC monitoring), the reaction mass was cooled to 0° C., quenched it with 2 ml of water and concentrated under vacuum. Added water (50 ml) and extracted with ethyl acetate (3×50 ml). The combined organic layer was dried over Na2SO4, filtered and concentrated under vacuum to get the product (0.10 g) that was carried forward to the next step without further purification.
