Procedure
To a 40-mL vial with magnetic stirbar at 25° C. was added 4-{3-[(5-Morpholin-4-yl-pyridine-3-carbonyl)-amino]-benzylamino}-quinazoline-8-carboxylic acid methyl ester (0.12 g, 0.24 mmol, 1 eq.) and THF (2 mL) and 2-propanol (2 mL). An approx. equal volume (i.e.; 2 mL) of concentrated aqueous ammonium hydroxide solution (28-30% soln.) was then added and stirring continued over the weekend (×96 hours). Water (15 mL) was added to the reaction mixture and a precipitate immediately began to form. The precipitate was collected and dried thoroughly in vacuo. The material required further purification via preparative HPLC. The isolated material was re-dissolved in THF (1 mL), iPrOH (1 mL), and DMSO (1 mL) to which concentrated aqueous ammonium hydroxide solution (28-30%) (1 mL) was added and heated at 50° C.×36 hours. H2O (10 mL) was added to the reaction mixture and the resulting white precipitate collected and dried thoroughly in vacuo to afford 50.2 mg (45% yield). LCMS (ESI) 484.2 (M+H).
