Bis(2-chloroethyl)amine → 2,4-Diamino-6-(bis-2-chloroethyl)aminomethylpteridine

Participants

Reaction Steps

To a stirred solution of 2.4 g (9.4 mmol) of 2,4-diamino-6-(bromomethyl)pteridine in 50 ml of N,N-dimethylacetamide was added 6 g (0.04 mol) of bis-(2-chloroethyl)amine, and the mixture was stirred at 50°-55° C. for 5 hours and then for 18 hours at room temperature. After filtering from a small amount of dark insoluble matter, the filtrate was diluted with 200 ml of water whereupon 2,4-diamino-6-bis(2-chloroethyl)-aminomethylpteridine separated as a light tan solid which was filtered, washed thoroughly with water and air dried; yield, 0.92 g (31%).
