Versuchsvorschrift

Tetrahydrofuran (10 mL) and 5 N aqueous sodium hydroxide solution (448 μL, 2.24 mmol) were added to 4-(5-(2-amino-pyridin-3-yl)-isoxazol-3-ylmethyl)-phenol (600 mg, 2.24 mmol) described in Manufacturing Example 5-1-1, which was irradiated by ultrasonic wave for 1 minute. The reaction solution was then concentrated under a reduced pressure to obtain a white solid. 2-Chloromethyl-5-fluoro-pyridine (359 mg, 2.46 mol) described in Manufacturing Example 41-2 and N,N-dimethylformamide (10 mL) were added to the resulting white solid and stirred for 1 hour at 60° C. After being cooled to room temperature, the reaction solution was partitioned into water and ethyl acetate. The organic layer was separated and concentrated under a reduced pressure. The residue was purified by NH silica gel column chromatography (heptane:ethyl acetate=1:1) to obtain the title compound (650 mg, 77%).
