Reaction Steps

Into a 25-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed 3-chloro-5-phenyl-1,2-thiazole-4-carboxylic acid (500 mg, 1.88 mmol, 1.00 equiv, 90%), chlorobenzene (2 mL), BH3 (3.1 mL, 3.00 equiv) at 0° C. The resulting solution was stirred for 12 h at 50° C. in an oil bath. The reaction was then quenched by the addition of 10 mL of sodium bicarbonate/H2O. The resulting solution was extracted with 3×10 mL of ethyl acetate and the organic layers combined. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:4). This resulted in 80 mg (18%) of (3-chloro-5-phenyl-1,2-thiazol-4-yl)methanol as a white solid.
