실험 절차

To a stirred solution of 2-[4-(2-chloro-4-fluoro-phenyl)-4H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1-thia-benzo[e]azulene-9-carbonitrile (90 mg; 0.21 mmol) in DMSO (3 ml) and MeOH (5 ml) was added K2CO3 (36 mg; 0.26 mmol) then H2O2 (30 μl of a 30% aqueous soln.). The reaction mixture was stirred at room temperature overnight (16 h) upon which time the methanol was removed on a rotary evaporator and the residue was diluted with water (40 ml). The resulting solid was collected by filtration, washed with water and dried to give 281 as a white solid (82 mg; 89%). δH (400 MHz, CDCl3) 3.15 (t, J=5.2, 2H), 4.34 (t, J=5.2, 2H), 5.50-6.30 (br s, 2H), 6.88 (s, 1H), 7.07 (d, J=8.4, 1H), 7.22-7.27 (m, 1H), 7.42-7.63 (m, 3H), 8.06 (d, J=2.0, 1H), 8.22 (s, 1H).
