Procedure
To a mixture of N-(4-bromo-2-fluorophenyl)-6-(3-chloropropoxy)-7-methoxyquinazolin-4-amine (1.25 g), K2CO3 (0.78 g) and a catalytic amount of KI in DMF (20 mL) was added tert-butyl hexahydropyrrolo[3,4-c]pyrrole-2(1H)-carboxylate (0.78 g) at room temperature. The reaction mixture was heated to 80° C. and stirred for 8 h, then diluted with water and extracted with CH2Cl2. The organic layer was dried over anhydrous Na2SO4 for 1 h and filtered. The filtrate was concentrated in vacuo and the residue was chromatographed with a silica gel column (eluting agent: 30:1 (v/v) DCM/MeOH) to give the title compound as a white solid (1.16 g, 66.50%).
