실험 절차

To an ice-cooled solution of 2-{4-[8-fluoro-2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diazabenzo[e]azulen-9-ylsulfanyl]piperidin-1-yl}isobutyramide from Example 8 (96 mg, 0.183 mmol) in DCM (10 mL) was added TFA (42 μL, 0.548 mmol) followed by a solution of m-CPBA (35 mg, 0.201 mmol) in DCM (2 mL). The resulting mixture was stirred for 30 min at 0° C. then volatiles were removed under reduced pressure. The crude material was purified by column chromatography (C18, gradient 10-50% MeOH in 0.5% TFA/H2O) and then loaded onto an Isolute® SCX-2 cartridge. The cartridge was washed with MeOH and the product was eluted with 0.5M NH3 in MeOH. The product containing fractions were concentrated in vacuo and further purified by column chromatography (Si-PCC, gradient 2-12% MeOH in DCM) affording 220 as a white solid (59 mg, 60%). LCMS: RT 2.54 min [M+H]+ 544.1. 1H NMR (DMSO, 400 MHz): δ 8.72 (1H, d, J=7.98 Hz), 7.93 (1H, s), 7.17-7.09 (2H, m), 6.86 (1H, s), 5.68-5.56 (1H, m), 4.67-4.50 (4H, m), 2.88-2.74 (3H, m), 2.26 (3H, s), 2.19-2.04 (2H, m), 1.92-1.84 (1H, m), 1.76-1.51 (3H, m), 1.50-1.42 (6H, m), 1.03 (6H, d, J=4.44 Hz)
