실험 절차

5-Hydroxymethyl-2-(phenylamino)pyrimidine (280 mg, 1.39 mmol) obtained in Step 3 was dissolved in DMF (10 mL), and imidazole (190 mg, 2.76 mmol) and tert-butyldimethylsilylchloride (420 mg, 2.79 mmol) were added to the solution, followed by stirring at room temperature for 2 hours. The reaction mixture was diluted with ethyl acetate and washed with water and saturated brine. The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:10) to obtain 5-(tert-butyldimethylsiloxymethyl)-2-(phenylamino)pyrimidine (423 mg, 82%).
