Potassium Carbonate → 2-((4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)-5-bromo-3-(2-chloro benzyl)quinazolin-4(3H)-one

Participants

Reaction Steps

To a stirred mixture of 5-bromo-3-(2-chlorobenzyl)-2-(chloromethyl)quinazolin-4(3H)-one, (8), (13.6 g, 30.7 mmol) and 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (1) (8.09 g, 30.7 mmol) in DMF (300 mL was added potassium carbonate (6.36 g, 46.0 mmol) and the reaction maintained at RT in the dark for 24 hr. The mixture was poured onto water (4.0 L) and the resulting suspension was stirred at RT for 1 hr. The precipitate was isolated by filtration and dried in vacuo to afford the title compound, Intermediate A, as a colourless solid (18.0 g, 94%); m/z 622/624 [M+H]+ (ES+).
