Lithium methylsulfinylmethylide

N -Alkylation of 7,8-dihydropteridines. Direct monoalkylation at N of 2,4-diamino-7,8-dihydropteridines (1) can be accomplished by treatment with 1.1 eq. of n-butyUithium in DMSO (the actual reagent is lithium methylsulfinylmethylide) and then with a slight excess of an alkyl halide. No substitution in... [Pg.174]
