実験手順

6-(Hydroxy(1-tosyl-1H-imidazol-4-yl)methyl)-N-methyl-2-naphthamide (8.2 g, 18.8 mmol) and manganese dioxide (14.7 g, 169.1 mmol) were added to N,N-dimethylacetamide (70 mL), and the mixture was stirred at 60° C. for 7 hr. The insoluble material was filtered off from the obtained reaction mixture at 60° C., and washed with N,N-dimethylacetamide (33 mL). The filtrate and washing were combined, and cooled to 40° C., water (49 mL) was added dropwise thereto, and the mixture was stirred at the same temperature for 0.5 hr or more, and then at room temperature for 1 hr or more to give crystals. The obtained crystals were collected by filtration, and washed with water (51 mL) to give wet crystals. The obtained wet crystals were dried under reduced pressure at an outside temperature of 50° C. to give crude crystals (6.6 g). Ethyl acetate (66 mL) were warmed to 40° C., and the crude crystals (6.6 g) were added thereto. The obtained mixture was warmed to 50° C., and stirred for 0.5 hr or more, and 13 mL of the solvent was evaporated under reduced pressure. The obtained residue was allowed to cool to room temperature, diisopropyl ether (53 mL) was added dropwise thereto at the same temperature, and the mixture was stirred to give crystals. The obtained crystals were collected by filtration, and washed with a mixed solvent (20 mL) of diisopropyl ether/ethyl acetate (1:1, volume ratio) to give wet crystals. The obtained wet crystals were dried under reduced pressure at an outside temperature of 50° C. to give N-methyl-6-[(1-tosyl-1H-imidazol-4-yl)carbonyl]-2-naphthamide (6.5 g, 15.0 mmol). yield 79%.
