실험 절차

To a solution of 8-bromo-4-(1-methyl-piperidin-4-yloxy)-2-phenyl-9,10-dihydro-4H-3,10a-diaza-benzo[f]azulene (example 231) (276 mg, 0, 55 mmole) in dimethylformamide (5 mL) in a screw-capped vial are added a 3M solution of methylamine in methanol (2.8 mL, 5.5 mmoles), copper(I) iodide (100 mg, 0, 52 mmole) and cesium carbonate (250 mg, 0.77 mmole). The vial is evacuated and filled with argon. The reaction mixture is stirred at 100° C. for 36 hours. Water and ammonia are added to the reaction mixture, and the aqueous phase is extracted three times with dichloromethane. Pooled organic extracts are dried over magnesium sulphate, filtered and the solvent is removed under reduced pressure. The residue is purified by preparative HPLC-MS (Waters AutoPurification HPLC/MS System, Sunfire Prep C18 5 μm OBD 30×150 mm column, eluents: water/0.1% formic acid (A) and acetonitrile/0.1% formic acid (B), focus gradient from 11% (B) to 21% (B) in 10 minutes) to afford methyl-[4-(1-methylpiperidin-4-yloxy)-2-phenyl-9,10-dihydro-4H-3,10a-diaza-benzo[f]azulen-8-yl]-amine melting at 189° C.
