Reaktionsschritte
To (1,5-dimethyl-1H-pyrazol-3-yl)methanol (5.01 g, 39.71 mmol) in DCM (80 mL) at 0° C. was cautiously added thionyl chloride (25 mL, 343.6 mmol). The cold bath was removed and the reaction mixture was stirred at ambient temperature for 3 hours. The reaction mixture was concentrated under reduced pressure to give crude product (7.32 g).
