Versuchsvorschrift

To a solution of 3-(1H-pyrazol-4-yl)-pyridin-2-ylamine (20 mg, 0.13 mmol) described in Manufacturing Example 32-1-4 in N,N-dimethylformamide (10 mL) was added sodium hydride (7.5 mg, 0.19 mmol, 60% in oil) under nitrogen atmosphere on an ice bath (0° C.), which was stirred for 30 minutes at room temperature. 1-Chloromethyl-4-phenoxy-benzene (32.8 mg, 0.15 mmol) described in Manufacturing Example 34-1-1 was then added to the mixture and stirred for 30 minutes at room temperature. The reaction mixture was partitioned into water and ethyl acetate at room temperature. The organic layer was washed with water and saturated aqueous sodium chloride, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under a reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate:heptane=2:1, then ethyl acetate only) to obtain the title compound (41 mg, 86%, purity: 90%).
