Procedure
To (2-(1-(2,2,2-trifluoroethyl)-1H-pyrazol-5-yl)pyridin-3-yl)methanol (408 mg, 1.59 mmol) in DCM (5 mL) was added SOCl2 (1.5 mL) at rt. The reaction mixture was stirred at rt for 4 h and concentrated to dryness. The crude solid was suspended in toluene and concentrated to dryness. The process was repeated three times and dried under vacuum to give 3-(chloromethyl)-2-(1-(2,2,2-trifluoroethyl)-1H-pyrazol-5-yl)pyridine hydrochloride (498 mg) as an off-white solid, which was used for next step without further purification.
