Procedure
(2E)-3-(4-Phenoxy-5H-pyrrolo[3,2-d]pyrimidin-6-yl)-2-propen-1-ol (1.0 g) was suspended in tetrahydrofuran (20 mL), and triethylamine (0.651 mL) and benzoyl chloride (0.86 mL) were sequentially added under ice-cooling. The mixture was stirred under ice-cooling for 2 hrs, diluted with ethyl acetate (200 mL) and washed with water (50 mL). The organic layer was dried over magnesium sulfate and concentrated under reduced pressure. The residue was separated and purified by basic silica gel column chromatography (eluent, hexane:ethyl acetate=80:20→0:100) to give the title compound (1.08 g) as crystals.
