Reaction Steps

To a mixture of 9-[4-carboxymethoxy-2-chloro-5-(2-fluoro-6-methoxybenzyloxy)-phenyl]-2-hydroxymethyl-6-methoxy-7,9-dihydro-8H-purin-8-one (0.1 g), 40% aqueous methylamine solution (0.06 mL), 1-hydroxybenzo[r]azole monohydrate (34 mg) and triethylamine (0.1 mL) in N,N-dimethylformamide (2 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (72 mg), and the mixture was stirred at 60° C. overnight. 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 brine, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: ethyl acetate−ethyl acetate/methanol=9/1) to give the title compound (54 mg).
