Hydrochloric Acid → 9-fluoro-5-{[4-[4-(1-methylethyl)-1-piperazinyl]-2-(methyloxy)phenyl]amino}-3-[(4-methylphenyl)sulfonyl]pyrrolo[2',3':4,5]pyrimido[6,1-b]quinazolin-7(3H)-one

Participants

Reaction Steps

To a pressurized vessel was added 2-({2-chloro-7-[(4-methylphenyl)sulfonyl]-7H-pyrrolo[2,3-d]pyrimidin-4-yl}amino)-5-fluorobenzamide (3.0 g, 6.54 mmol), 4-[4-(1-methylethyl)-1-piperazinyl]-2-(methyloxy)aniline (2.11 g, 8.5 mmol), potassium iodide (<10 mg) and hydrochloric acid as a 4.0M solution in dioxanes (ca 10 mL). The resulting suspension was stirred until all solids had completely dissolved (24 hr.) The reaction was poured into into saturated sodium bicarbonate and diluted with dichloromethane. The organic layer was dried over sodium sulfate, volatiles removed under reduced pressure, and the solids triturated with diethyl ether to afford 9-fluoro-5-{[4-[4-(1-methylethyl)-1-piperazinyl]-2-(methyloxy)phenyl]amino}-3-[(4-methylphenyl)sulfonyl]pyrrolo[2′,3′:4,5]pyrimido[6,1-b]quinazolin-7(3H)-one (3.27 g, 76% yield) of sufficient purity for use in subsequent transformations. ESIMS (M+H)=656.
