Procedure
7-Nitro-1,2,3,4-tetrahydronaphthalen-1-ol (1.0 g, 5.2 mmol) was dissolved in a mixture of DCM (10 mL) and pyridine (10 mL). Then, the reaction mixture was cooled to 0° C. and methane sulphonyl chloride (0.44 mL, 5.7 mmol) was added dropwise, and the reaction mixture was stirred at 60° C. for 2 hours. Next, the reaction mixture was cooled to room temperature and then diluted with ethyl acetate, and washed with 1N HCl, saturated NaHCO3, and brine. The organic solution was dried (Na2SO4) and concentrated to give methanesulfonic acid 7-nitro-1,2,3,4-tetrahydronaphthalen-1-yl ester. Yield 1.34 g (95%). LCMS (ESI): calc. C11H13NO5S=271; obs. low ionization.
