実験手順
Methanol (3 mL) and 1 N aqueous sodium hydroxide solution (0.18 mL) were added to 4-(5-(2-amino-pyridin-3-yl)isoxazol-3-ylmethyl)-phenol (50 mg, 0.19 mmol) described in Manufacturing Example 5-1-1, which was then dissolved by irradiating ultrasonic wave. This solution was concentrated under a reduced pressure. To the resulting residue were added 2-chloromethyl-6-methyl-pyridine (31.8 mg, 0.22 mmol) described in Manufacturing Example 10-1-1 and N,N-dimethylformamide (2 mL), which was stirred for 20 minutes at 60° C. The reaction solution was partitioned into water and ethyl acetate. The organic layer was separated, and the solvent was evaporated under a reduced pressure. The residue was purified by NH silica gel column chromatography (heptane:ethyl acetate=1:1) to obtain the title compound (36 mg, 51.7%).
