実験手順

To an ice-cooled solution of 2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-9-(1-isopropylpiperidine-4-sulfinyl)-8-methyl-4,5-dihydro-6-oxa-1,3a-diazabenzo[e]azulene 225 (30 mg, 0.061 mmol) in DCM (3 mL) was added TFA (24 μL, 0.306 mmol) followed by a solution of m-CPBA (14 mg, 0.0796 mmol) in DCM (1 mL). The resulting mixture was stirred for 3 h at 0° C. then volatiles were removed under reduced pressure. The crude material was purified by column chromatography (C18, gradient 20-50% MeOH in 0.5% TFA/H2O) and then loaded onto an Isolute® SCX-2 cartridge. The cartridge was washed with MeOH and the product eluted with 0.5M NH3 in MeOH. The basic fractions were combined and concentrated in vacuo and the resulting residue was purified by column chromatography (Si-PCC, gradient 3-15% MeOH in DCM) affording 243 as a white solid (14 mg, 44%). LCMS: RT 2.83 min [M+H]+ 513.1. 1H NMR (CD3OD, 400 MHz): δ 9.08 (1H, s), 7.76 (1H, s), 7.10 (1H, s), 5.93-5.80 (1H, m), 4.63-4.53 (4H, m), 3.21-3.10 (1H, m), 3.00 (2H, bd, J=11.56 Hz), 2.77-2.67 (1H, m), 2.64 (3H, s), 2.37 (3H, s), 2.24 (2H, t, J=12.17 Hz), 1.97 (2H, d, J=12.67 Hz), 1.87-1.74 (2H, m), 1.56 (6H, d, J=6.65 Hz), 1.04 (6H, d, J=6.56 Hz)
