Reaction Steps

To a 40-mL vial with magnetic stirbar at r.t. was added the 4-{3-[(2-Chloro-pyridine-4-carbonyl)-amino]-benzylamino}-quinazoline-8-carboxylic acid methyl ester (0.6 g, 1.34 mmol, 1 eq.) and THF (6 mL) and 2-propanol (6 mL). An approx. equal volume (i.e.; 6 mL) of concentrated aqueous ammonium hydroxide solution (28-30% soln.) was then added and stirring continued overnight. Water (15 mL) was added to the reaction mixture and a white precipitate immediately began to form. The precipitate was collected and dried thoroughly in vacuo and afforded 314 mg (55% yield). Material was carried on to the next synthetic step without further purification. LCMS (ESI) 433 (M+H)
