Reaction Steps

To a toluene (20.0 mL) solution of (5-bromo-pyridin-2-yl)-methanol (4.70 g, 25.0 mmol) described in Manufacturing Example 54-1-1 was added dropwise thionyl chloride (3.65 mL, 50.1 mmol) on an ice bath (0° C.) under nitrogen atmosphere, which was stirred for 5 minutes at room temperature. The solvent was evaporated under a reduced pressure to obtain the title compound (4.2 g, 69.2%) as a hydrochloride.
