실험 절차

To a suspension of (1-{3-[2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-8-yl]-azetidine-1-carbonyl}-cyclopropyl)-carbamic acid tert-butyl ester (225 mg, 0.41 mmol) in MeOH (3.1 mL) was added 4N HCl/dioxan (1.0 mL, 4.1 mmol) and the reaction mixture was stirred for 18 hours. The resulting solid was filtered off and washed with diethyl ether before being partitioned between DCM and an aqueous saturated sodium bicarbonate solution. The phases were separated and the aqueous phase was extracted with DCM (×2). The combined organic extracts were washed with brine, dried (Na2SO4) and concentrated in vacuo. The resultant residue was purified by flash chromatography (SiO2, 0-8% 2N NH3/MeOH in DCM). The resulting solid was suspended in ether and collected by filtration to give 425 as a white solid (108 mg, 59%). LCMS: RT=7.96 min, [M+H]+=451. 1H NMR δ (ppm) (DMSO-d6): 8.35 (1H, d, J=8.20 Hz), 8.02 (1H, s), 7.20 (1H, dd, J=8.22, 1.81 Hz), 7.05 (1H, s), 5.86-5.78 (1H, m), 4.59 (2H, t, J=9.01 Hz), 4.40 (2H, t, J=5.07 Hz), 4.20 (2H, d, J=7.67 Hz), 3.85 (1H, t, J=7.50 Hz), 3.44 (2H, t, J=5.08 Hz), 2.18 (2H, s), 1.58 (6H, d, J=6.59 Hz), 1.09-1.06 (2H, m), 0.70 (2H, q, J=3.28 Hz)
