Abstract
A number of nitrogen heterocycles reacted with 4-methoxy-3-nitrobenzyl chloride in dimethyl-formamide in the presence of potassium carbonate to give the corresponding N-(4-methoxy-3-nitrobenzyl) derivatives. The reaction of 5-fluoro-1,3-bis(4-methoxy-3-nitrobenzyl)pyrimidine-2,4(1H,3H)-dione with aqueous methylamine afforded N,N′-bis(4-methylamino-3-nitrobenzyl)urea, whereas analogous reaction with 1-(4-methoxy-3-nitrobenzyl)-2-(methylsulfanyl)-1H-benzimidazole resulted in substitution of the methoxy group by methylamino.
