실험 절차

To a mixture of 8-azetidin-3-yl-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene TFA salt 235 (100 mg, 0.2 mmol) in dry DCM (2 mL) was added triethylamine (60 μL, 0.4 mmol) and the reaction mixture was stirred for 1 hour. The mixture was washed with water followed by brine, dried (Na2SO4) and then treated with triethylamine (30 μL, 0.2 mmol) followed by 2-chloroethane-sulfonyl chloride (42 μL, 0.4 mmol) in dry DCM (1 mL). The reaction mixture was stirred at RT for 18 hours then diluted with DCM and washed with water followed by brine, dried (Na2SO4) and concentrated in vacuo to give 8-(1-Ethenesulfonyl-azetidin-3-yl)-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene as a light brown oil (75 mg, 82%). 1H NMR δ (ppm) (CDCl3): 8.39 (1H, d, J=8.22 Hz), 7.93 (1H, s), 7.16 (1H, dd, J=8.22, 1.98 Hz), 7.02 (1H, d, J=1.91 Hz), 6.61 (1H, dd, J=16.50, 9.95 Hz), 6.39 (1H, d, J=16.66 Hz), 6.18 (1H, d, J=9.95 Hz), 5.93-5.87 (1H, m), 4.45-4.39 (2H, m), 4.28-4.22 (2H, m), 4.07-3.97 (2H, m), 3.81 (1H, t, J=7.81 Hz), 3.46-3.40 (2H, m), 1.64 (6H, d, J=6.65 Hz)
