2-(CHLOROMETHYL)-purine-6(9 H)-one (3) was synthesized from reaction of the 5-amino-imidazole-4-carboxamide 1 with 2-chloroacetyl chloride. Also, products 4-7 were obtained from reacting 3 with different reagents. Treatment of 1 with ethyl chloroformate / DMF reagent mixture afforded 9-aryl-1,9-dihydro-6H-purin-6-one (9). Product 9 when reacted with some alkyl iodides gave 7-alkylpurinium iodide salts (10) rather than the expected products of type 11 or 12. N-substituted – purin -6- amines 14a-g, N1-(purin-6-yl) - benzene-1,2-diamine 14h and hydrazide 14i were synthesized upon treating product 9 with phosphoryl chloride followed by reaction with some selected amines or hydrazides . Screening for selected examples from the synthesized products 14 towards wheat plant growth regulation was reported.
