6-(Bromomethyl)-2,4-diaminopteridine hydrobromide

摘要

A pteridine compound having the formula of 6-(bromomethyl)-2,4-diaminopteridine hydrobromide. 2,4-diamino-6-pteridine-methanol.HBr is reacted with triphenylphosphine dibromide or phosphorus tribromide to form 6-(bromomethyl)-2,4-diaminopteridine hydrobromide. The bromine atom in the molecule can then be replaced with the functional group, N-[4-(methylamino)-benzoyl]-L-glutamic acid in the case of methotrexate and N-(4-aminobenzoyl)-L-glutamic acid in the case of aminopterin.
