実験手順

To N-(5-((tert-butyldimethylsilyloxy)methyl)isoxazol-3-yl)-7-(6,7-dimethoxyquinolin-4-yloxy)-2,3-dihydrobenzo[b][1,4]oxazine-4-carboxamide (7) (50 mg, 0.084 mmol) was added 2 N HCl in EtOH (5 mL) at RT. After 15 min, the solid had dissolved and the solution was stirred at RT for an additional 2 hrs at which time a white precipitate formed. The mixture was cooled to 0° C., filtered, and the isolated solid was washed with cold EtOH. The solid was dried in vacuo to afford 7-(6,7-dimethoxyquinolin-4-yloxy)-N-(5-(hydroxymethyl)isoxazol-3-yl)-2,3-dihydrobenzo[b][1,4]oxazine-4-carboxamide hydrochloride (33 mg, 83% yield). MH+=479.2.
