HCID 513479062-[2-(2-Chloro-phenyl)-2H-[1,2,4]triazol-3-yl]-9-piperidin-4-yl-4,5-dihydro-2H-6-oxa-1,2-diaza-benzo[e]azulene

Procedure

2-[2-(2-Chloro-phenyl)-2H-[1,2,4]triazol-3-yl]-9-piperidin-4-yl-4,5-dihydro-2H-6-oxa-1,2-diaza-benzo[e]azulene was prepared similarly to 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 from 4-{2-[2-(2-chloro-phenyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-2H-6-oxa-1,2-diaza-benzo[e]azulen-9-yl}-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (490 mg, 0.9 mmol). The crude salt was partitioned between DCM and saturated aqueous sodium hydrogen carbonate, then the aqueous layer was extracted with DCM. The combined organic extracts were dried (Na2SO4), filtered and concentrated in vacuo. The resultant residue was subjected to reverse phase HPLC (Gemini C18 column, gradient MeOH in H2O+0.1% HCO2H) to give 154 (80 mg, 18%) as the mono formate salt. 1H NMR (400 MHz, DMSO-d6): δ 8.44 (s, 1 H); 8.39 (s, 1 H); 8.27 (s, 1 H); 7.81-7.68 (m, 3 H); 7.64 (td, J=7.60, 1.51 Hz, 1 H); 7.09-7.03 (m, 2 H); 6.90 (d, J=8.28 Hz, 1 H); 4.19 (t, J=5.06 Hz, 2 H); 3.32 (d, J=12.42 Hz, 2 H); 3.04 (t, J=5.01 Hz, 2 H); 2.89 (dd, J=13.45, 11.09 Hz, 2 H); 2.54-2.56 (m, 1 H); 1.69 (d, J=13.20 Hz, 2 H); 1.58-1.45 (m, 2 H). LCMS: RT=7.99 min, M+H+=447
