Reaction Steps

A suspension of 2-(1-amino-2-methyl-propyl)-3-benzyl-7-chloro-3H-quinazolin-4-one (1.0 g, 2.93 mmol), 2-(4-bromo-3-oxo-butyl)-isoindole-1,3-dione (867 mg., 2.93 mmol, prepared as described in WO 89/10360), and potassium carbonate (405 mg, 2.93 mmol) in DMF (14 mL) was stirred at room temperature for 80 minutes. The reaction was diluted with water and the resulting white solid (1.6 g.) was used in the subsequent step without further purification.
