Procedure

To a mixture of [5-(2-aminopyridin-3-yl)isoxazol-3-yl]methanol (0.19 g, 1 mmol) and N,N-dimethyl acetamide (1 mL) was added a mixture of thionyl chloride (0.15 mL, 2 mmol), benzotriazole (0.26 g, 2.2 mmol) and tetrahydrofuran (1 mL) under an ice cooling, which was stirred at room temperature for 30 minutes. To the reaction mixture were added water and 5N aqueous sodium hydroxide to adjust basic, then extracted with ethyl acetate, and the organic layer was washed with saturated sodium chloride water. The solvent was evaporated under a reduced pressure to obtain the title compound (0.21 g) as a pale yellow solid.
