Hydrochloric Acid → (2-Amino-6-iodoquinazolin-4-yl)isoindolin-2-ylmethanone

Participants

Reaction Steps

24.50 g of tert-butyl {2-[2-(1,3-dihydroisoindol-2-yl)-2-oxoacetyl]-4-iodophenyl}carbamate are dissolved in 500 ml of acetonitrile under argon. 0.756 g of caesium fluoride is added, and 16.887 ml of bis(trimethylsilyl)-carbodiimide are added dropwise to the solution over 5 min. The mixture is stirred at room temperature for 15 min, and 400 ml of dichloromethane are added. After addition of 400 ml of hydrochloric acid (1N), the product precipitates out as a white solid. Yield: 14 g of (2-amino-6-iodoquinazolin-4-yl)-(1,3-dihydroisoindol-2-yl)methanone; LC-MS retention time: 1.655 min;
