Versuchsvorschrift

SnCl2 (8.5 g) dissolved in 8.5 mL of conc. HCl was added to the solution of 6-nitroquinazoline in 42.5 mL of 6 N HCl at 0° C. The reaction mixture was neutralized with KOH 10 minutes later and then extracted with diethyl ether (Et2O) and EtOAc. The product 6-aminoquinazoline was obtained (0.67 g) after the removal of the solvent.
