実験手順

To a solution of 1-[4-[2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yl]-1-(tetrahydro-pyran-2-yl)-1H-imidazol-2-yl]-2-methyl-propan-2-ol (735 mg, 1.42 mmol) in EtOH (15 mL) was added a solution of hydrogen chloride in MeOH (7.1 mL, 28.4 mmol). The reaction mixture was heated at reflux for 5 h, cooled to r.t. and concentrated. Saturated NaHCO3 solution was added slowly and the reaction mixture was extracted with EtOAc. The combined organic layer was dried over Na2SO4, filtered and concentrated. The crude product was purified by prep-TLC (DCM:MeOH=8:1) to give 290 as a yellow solid (74 mg, 12%). 1H NMR (CDCl3, 400 MHz): δ 8.44 (d, J=8.4 Hz, 1H), 7.89 (s, 1H), 7.58 (s, 1H), 7.43-7.36 (m, 2H), 7.28 (s, 1H), 5.95-5.91 (m, 1H), 4.45-4.02 (m, 4H), 2.97 (s, 2H), 1.60 (d, J=6.8 Hz, 6H), 1.30 (s, 6H). MS: (ESI, m/z)=434 [M+H]+.
