Versuchsvorschrift

To thionyl chloride (8.0 ml) was gradually added at 0° C. 3-hydroxymethyl-1-methyl-1H-1,2,4-triazole (0.60 g), which was refluxed for 3 hours. The reaction mixture was concentrated under reduced pressure, to which was added diethyl ether. Resulting powder was crystallized from a mixture of ethanol and diethyl ether to give 3-chloromethyl-1-methyl-1H-1,2,4-triazole hydrochloride (1.0 g) as colorless needles, m.p. 69°-70° C.
