6.710 g (52.785 mmol) of (3-fluoropyridin-4-yl)methanol was put in 29 ml acetonitrile and heated to 50° C. Then a solution of 7.701 ml thionyl chloride in 14.5 ml acetonitrile was added dropwise and the reaction mixture was stirred for 4 h at 50° C. Then the reaction mixture was concentrated by evaporation and was co-distilled three times with dichloromethane. After drying under high vacuum, 10.27 g of the title compound was obtained, which was used in the next step without further purification.
