実験手順

To a solution of 0.0415 g (0.23 mmol) 16 in 3 mL DMF was added 0.0169 g (0.26 mmol) sodium azide. After a 3 h, an additional 0.0033g (0.05 mmol) portion of sodium azide was added. After 24 h at room temperature, the reaction mixture was diluted with 50 mL EtOAc and washed with 20 mL brine. The aqueous layer was extracted with 10 mL EtOAc. The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo. Purification by flash chromatography (10×175 mm silica gel, linear gradient 5-20% EtOAc:hexane) produced 17. 1H NMR (CDCl3, 400 MHz) δ 9.318 (s, 1H, ArH); 8.637 (d, 1H, J=6.10 Hz, ArH); 8.010 (d, 1H, J=7.94 Hz, ArH); 7.822 (d, 1H, J=6.10 Hz, ArH); 7.713 (d, 1H, J=7.02 Hz, ArH); 7.617 (dd, 1H, J=7.17, 8.09 Hz, ArH); 4.774 (s, 1H, ArH); MS (Electrospray): m/z 185.0 (M+H).
