Reaction Steps

A mixture of (2-chloro-quinazolin-4-yl)-dimethyl-amine obtained in step B of example 1 (5.1 g, 28.9 mmol) and 1-Benzyl-pyrrolidin-3-ylamine (5.1 g, 28.9 mmol) in BuOH (8 mL) was stirred at reflux for 26 hr, poured into saturated aqueous NaHCO3, and the aqueous layer was extracted with CHCl3 (three times). The combined organic layer was dried over MgSO4, filtered, concentrated, and purified by flash chromatography (NH-silica gel, 10% to 16% EtOAc in hexane) to give N2-(1-benzyl-pyrrolidin-3-yl)-N4,N4-dimethyl-quinazoline-2,4-diamine (3.37 g, 50%) as a pale yellow solid.
