실험 절차
To a solution of 4,4-dimethyl-7-{2-[(pyridazin-4-ylmethylene)-amino]-benzoylamino}-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (Example 121, Step B, 200 mg, 0.41 mmol) in EtOAC (1 mL). Concentrated HCl in EtOAc (2 mL) was added. The reaction was stirred for 5 h under N2 atmosphere at RT. The solid was filtered off and dissolved in water. The aqueous solution was basified to pH 11-14 using 5 N NaOH. The resulting precipitate was filtered, washed with water and dried under vacuum, to obtain the titled compound as a tan solid. MS (ES+): 388.0 (M+H)+. Calc'd for C23H25N5O: 387.21.
