참여 물질

반응 단계

To a mixture of 3-(1H-pyrazol-4-yl)-pyridin-2-ylamine (20 mg, 0.13 mmol) described in Manufacturing Example 32-1-4 and N,N-dimethylformamide (1 mL) was added sodium hydride (6.8 mg, 0.19 mmol, 66% in oil), which was stirred for 30 minutes at room temperature. 1-Butoxymethyl-4-chloromethyl-benzene (29 mg, 0.14 mmol) described in Manufacturing Example 33-1-4 was added to the reaction mixture at room temperature, and stirred for 1.5 hours at 40° C. The reaction mixture was cooled and partitioned into water and ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride, and the solvent was evaporated under a reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate:heptane=2:1) to obtain the title compound (33 mg, 78%).
