Hydrochloric Acid → HCID 59309761, compound

Participants

Reaction Steps

To a mixture of 2-aminomethyl-9-[2-chloro-5-(2-fluoro-6-methoxybenzyloxy)-4-methoxyphenyl]-6-methoxy-7,9-dihydro-8H-purin-8-one (94 mg) and pyridine (0.1 mL) in methylene chloride (3 mL) was added acetic anhydride (0.055 mL), and the mixture was stirred at room temperature for 5 days. The reaction mixture was poured into 1 mol/L hydrochloric acid, and the resulting mixture was extracted with ethyl acetate. The extract was washed with water and brine, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=1/1−ethyl acetate). The obtained product was suspended in diethyl ether, and collected by filtration. The collected material was dried under reduced pressure to give the title compound (44 mg).
