实验步骤: To a suspension of 2-(2-Isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a,9-triaza-benzo[e]azulen-8-ol from Example 93 (137 mg, 0.44 mmol) in NMP (1.2 mL) was added sodium hydride (60% in mineral oil, 21 mg, 0.53 mmol). The reaction mixture was stirred at RT for 45 min, then at 45° C. for 45 min then cooled to RT. Phenyl trifluorosulphonimide (189 mg, 0.53 mmol) was added and the reaction stirred at RT for 1 h. 3,8-diaza-bicyclo[3.2.1]octan-2-one (69 mg, 0.48 mmol) and triethylamine (77 μL, 0.44 mmol) were added and the reaction mixture heated at 100° C. for 72 h then 120° C. for 7 h. The reaction mixture was cooled to RT, quenched with water and the resulting solid filtered and dried in vacuo. The resultant solid was loaded onto an Isolute SCX-2 cartridge, washed with methanol and eluted with 2M ammonia in methanol. Basic fractions were combined and concentrated in vacuo, the resultant residue was subjected to flash chromatography (SiO2, gradient 0 to 10% methanol in DCM) to give 466 (54 mg, 29%).
