Reaction Steps

A solution of 6.4 g of pyrrolidine in 50 ml of tetrahydrofuran was added to 10 g of 2-chloro-4-(2-diethylaminoethylamino)quinazoline hydrochloride in 100 ml of tetrahydrofuran. The reaction mixture was stirred at ambient temperature for about one hour and then was heated for 5 hours. The reaction mixture was poured into ice-water, made alkaline by the addition of dilute aqueous sodium hydroxide solution, and extracted with ether. The ether extract was washed with water, dried over anhydrous sodium sulfate, filtered, and evaporated. The residue, a gummy solid, was triturated with about 5 ml of hexane, and the resulting mixture was chilled overnight in a refrigerator. The mixture then was filtered and the solid obtained was recrystallized from aqueous ethanol to give 2 g of 2-pyrrolidinyl-4-(2-diethylaminoethylamino)quinazoline; m.p. 87°-90°. The following analytical data were obtained:
