실험 절차

To a solution of Example 3 (0.125 g, 0.377 mmol) and triethylamine (0.131 mL, 0.943 mmol) in dichloromethane (3.0 mL) was added dropwise methanesulfonyl chloride (0.064 mL, 0.830 mmol). The reaction mixture was stirred for 2 hours at ambient temperature and then concentrated. The residue was dissolved in a mixture of dioxane (5 mL) and 1M sodium hydroxide (2 mL) and heated for 1 hour at 90° C. The reaction mixture was cooled and diluted with ethyl acetate, brought to pH 7 with 1 M HCl and partitioned. The organic layer was washed with brine, dried (Na2SO4), filtered, and concentrated. The residue was purified by flash chromatography (silica gel, 0-4% methanol in dichloromethane) to afford 0.20 g (77%) of the title compound. 1H NMR (300 MHz, DMSO-d6) δ 3.02 (s, 3H) 3.48 (s, 3H) 6.23-6.30 (m, 1H) 6.85 (d, J=7.46 Hz, 2H) 6.99 (t, J=7.29 Hz, 1H) 7.04 (d, J=8.82 Hz, 1H) 7.20-7.29 (m, 5H) 7.39 (d, J=2.71 Hz, 1H) 9.72 (s, 1H) 12.01 (s, 1H).
