Reaction Steps

To a solution of (4-methylthiazol-2-yl)methanol (0.423 g, 3.27 mmol) in toluene (7 mL) was added thionyl chloride (0.478 mL, 6.55 mmol) dropwise. The mixture was heated to 65° C. and stirred for 1 hour. The mixture was concentrated under reduced pressure and the residue was triturated with ether. The solids were collected by filtration to afford 2-(chloromethyl)-4-methylthiazole hydrochloride (0.427 g, 71% yield) as pale yellow solids.
