Procedure
With cooling with ice, 0.16 mL of methanesulfonyl chloride and 0.29 mL of triethylamine were added to a tetrahydrofuran (5 mL) solution of 200 mg of 7-nitro-1,2,3,4-tetrahydronaphthalen-1-ol obtained according to the method described in WO2004/087124, and stirred for 1 hour. The insoluble matter was removed through filtration through Celite, the solvent was evaporated away from the filtrate, the residue was dissolved in 3 mL of N,N-dimethylformamide, then 1.55 mL of 2 M dimethylamine/tetrahydrofuran solution was added to it, and stirred overnight at 60° C. After left cooled, water was added to the reaction solution, and then diluted with ethyl acetate. The organic layer was washed with water and saturated saline water, and dried with anhydrous sodium sulfate. The solvent was evaporated away, and the residue was purified through silica gel column chromatography (hexane/ethyl acetate) to obtain 100 mg of the entitled compound as a yellow oil.
