实验步骤: To a suspension of 2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-8-piperidin-4-yl-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulene hydrochloride (150 mg, 0.35 mmol) in DCM (2 mL) was added triethylamine (107 μL, 0.77 mmol). The resultant mixture was stirred for 10 minutes before the addition of 2-chloro-N-ethyl-acetamide (46 mg, 0.38 mmol) and tetrabutylammonium iodide (13 mg, 0.04 mmol). The reaction was stirred at RT for 4 days before the reaction was washed with sodium hydrogen carbonate solution (sat. aq.). The aqueous phase was extracted with 10% MeOH in DCM (×3) and the combined organic layers dried (Na2SO4) then concentrated in vacuo. The resultant residue was purified by flash column chromatography (SiO2, gradient 0-10% MeOH in DCM) affording 276 (91 mg, 0.19 mmol, 55%). LCMS: RT=2.75 min, [M+H]+=478. 1H NMR δ (ppm) (CDCl3): 8.43 (1H, d, J=8.29 Hz), 7.59 (1H, s), 7.16 (1H, s), 7.00 (1H, dd, J=8.34, 1.81 Hz), 6.88 (1H, d, J=1.76 Hz), 5.91-5.80 (1H, m), 4.48-4.44 (2H, m), 4.42-4.37 (2H, m), 3.37-3.26 (2H, m), 3.06-2.88 (4H, m), 2.57-2.47 (1H, m), 2.38 (3H, s), 2.30 (2H, s), 1.87 (2H, d, J=12.74 Hz), 1.76 (2H, s), 1.54 (6H, d, J=6.65 Hz), 1.15 (3H, t, J=7.26 Hz). was washed with sodium hydrogen carbonate solution (sat. aq.)
