実験手順

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 (310 mg, 0.72 mmol) in DCM (6 mL) and TEA (0.3 mL, 2.16 mmol) was sonicated and stirred before adding N,N-dimethyl-2-chloroacetamide (98 mg, 0.8 mmol) and TBAI (28 mg, 0.072 mmol) and the reaction mixture stirred for 72 h at RT before being concentrated in vacuo. The resultant residue was partitioned between water and DCM and the aqueous extracted five times with DCM, the combined organic extracts dried (Na2SO4), filtered and concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 0 to 10% methanol in DCM) then triturated in diethyl ether to give 329 as a white solid (129 mg, 38%). LCMS: RT=2.71 min, [M+H]+=478. 1H NMR 400 MHz (CDCl3) δ: 8.44 (1H, d, J=8.30 Hz), 7.61 (1H, s), 7.04 (1H, d, J=8.43 Hz), 6.91 (1H, s), 5.91 (1H, t, J=6.63 Hz), 4.45 (4H, d, J=14.92 Hz), 3.39 (2H, m), 3.11 (2H, m), 3.10 (3H, s), 2.99 (1H, m), 2.98 (3H, s), 2.54 (2H, m), 2.41 (3H, s), 1.90 (4H, s), 1.57 (6H, d, J=6.65 Hz)
