실험 절차

A mixture of 9-piperidin-4-yl-2-[2-(2,2,2-trifluoro-ethyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1,10b-diaza-benzo[e]azulene (180 mg, 0.43 mmol) in DMF (1 mL) was treated with potassium carbonate (89 mg, 0.65 mmol) and bromo acetamide (77 mg, 0.56 mmol) and then stirred at RT for 18 h. The reaction mixture was partitioned between ethyl acetate and water, the aqueous layer extracted with ethyl acetate and the combined organic extracts dried (Na2SO4), filtered and concentrated in vacuo. The resultant residue was triturated in diethyl ether to give 143 as a pale yellow solid (115 mg, 54%). 1H NMR (DMSO-d6, 400 MHz): δ 8.21 (s, 1H); 7.75 (d, J=2.2 Hz, 1H); 7.28 (dd, J=8.4, 2.2 Hz, 1H); 7.20 (d, J=8.3 Hz, 1H); 7.15 (s, 2H); 6.97 (s, 1H); 5.73 (q, J=8.8 Hz, 2H); 4.49 (t, J=6.0 Hz, 2H); 3.20 (t, J=6.0 Hz, 2H); 2.96-2.85 (m, 4H); 2.62-2.52 (m, 1H); 2.24-2.14 (m, 2H); 1.84-1.66 (m, 4H). LCMS: RT=6.55 min, M+H+=476
