Reaction Steps

6-(4-Methoxyphenyl)-5H-pyrrolo[3,2-d]pyrimidin-4-ol (500 mg) was suspended in N,N-diethylaniline (1.11 mL)/1,2-dichloroethane (3.73 mL), phosphorus oxychloride (2.29 mL) was added, and the mixture was stirred with heating at 110° C. for 2 hrs. After cooling to room temperature, the reaction mixture was treated with ice water (20 mL), and adjusted to pH 7 or above with aqueous ammonia. After diluting with tetrahydrofuran (500 mL), the mixture washed with saturated brine (50 mL). The organic layer was dried over magnesium sulfate and concentrated under reduced pressure. The residue was separated and purified by silica gel column chromatography (eluent, hexane:ethyl acetate=80:20→20:80) to give the title compound (25 mg).
