Procedure
1.07 g of 3-t-butyl-1H-pyrazole-1-ylmethanol was dissolved to 140 ml of dichloromethane. 2 ml of thionyl chloride was added to the solution, followed by stirring at room temperature for overnight. The reaction mixture was concentrated under reduced pressure to obtain 1.66 g of 3-t-butyl-1-(chloromethyl)-1H-pyrazole hydrochloride.
