反応手順

To a solution of the N-(2,4-dimethoxybenzyl)-2-fluoropyrimidin-4-amine (2.50 g, 9.50 mmol) prepared in Example 95a and benzyl alcohol (1.97 mL, 19.0 mmol) in DMF (48 mL), sodium hydride (0.90 g, 23.7 mmol) was added, and the reaction solution was stirred at room temperature for 6 hours. To the reaction solution, an aqueous ammonium chloride solution (200 mL) was added, followed by extraction with ethyl acetate (100 mL). The thus obtained organic layer was washed twice with water (200 mL) and dried over anhydrous sodium sulfate. After vacuum concentration, the residue was purified with silica gel chromatography (hexane/ethyl acetate=1:2) to yield the title compound (3.29 g, 99%) as a colorless amorphous solid.
