Reaction Steps

Into a 25-mL round-bottom flask, was placed (3-chloro-5-phenyl-1,2-thiazol-4-yl)methanol (80 mg, 0.34 mmol, 1.00 equiv, 97%), MsCl (81.6 mg, 0.72 mmol, 2.00 equiv), TEA (107.7 mg, 1.06 mmol, 3.00 equiv), dichloromethane (1.5 mL). The resulting solution was stirred for 1 h at 20° C. The reaction was then quenched by the addition of 5 mL of water. The resulting solution was extracted with 3×5 mL of ethyl acetate and the organic layers combined and dried over anhydrous sodium sulfate. The solids were filtered out. The resulting mixture was concentrated under vacuum. This resulted in 85 mg (96%) of 3-chloro-4-(chloromethyl)-5-phenyl-1,2-thiazole as yellow oil.
