Versuchsvorschrift

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), potassium carbonate (89 mg, 0.65 mmol) and 2-(2-bromo-ethoxy)-tetrahydro-pyran (97 L, 0.65 mmol) was heated at 50° C. for 18 h. The cooled 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 subjected to flash chromatography (SiO2, gradient 0 to 10% MeOH (+2M NH3) in DCM) to give a colourless oil. The oil was dissolved in methanol and treated with 1M HCl in methanol (2 mL, 2 mmol) and the reaction mixture stirred for 2 h at RT before concentrating in vacuo. The resultant residue was triturated in a mixture of diethyl ether and methanol to give 142 as a pale yellow solid (115 mg, 54%). 1H NMR (DMSO-d6, 400 MHz): δ 9.81 (br s, 1H); 8.22 (s, 1H); 7.70 (s, 1H); 7.32-7.24 (m, 2H); 6.99 (s, 1H); 5.72 (q, J=8.7 Hz, 2H); 5.36 (br s, 1H); 4.51 (t, J=6.0 Hz, 2H); 3.80 (t, J=4.9 Hz, 2H); 3.67-3.57 (m, 2H); 3.22-3.06 (m, 6H); 2.97-2.85 (m, 1H); 2.10-2.00 (m, 4H). LCMS: RT=6.62 min, M+H+=463.1
