|b The present work is aimed to synthesize some new heterocyclic compounds containing pyrrolo[2,3-d]pyrimidines, \ Our approach to the synthesis of the target compounds started through the hydrolysis of 6-ethylthio-4-methyl-2-(2'',4'- \ dimethoxyphenyl)pyi imidine-5-carbonitrile (2) by refluxing in ethanol containing sodium hydroxide to give the corresponding sodium salt derivative (3) which in turn wais acidified to give 5-cyano-4-niethyl-2-(2 A- dimethoxyphenyl)pyrimidin-6(H)one (4). Chlorination of the hydroxy derivative (4) afforded 6-Chloro-4-methyl-2-(2\\4'- dimethoxyphenyl)pyrimidin-5-carbonitrile (5), which reacted with ethyl glycinate hydrochloride.to give Ethyl (5-cyano-4-methyl-2-(2\\4'- dimethoxyphenyl)yrimidin-6-yloxy)acetate (6),which underwent cyclization to give the ethyl 5-amino-4-methyl-2-(2,4'-dimethoxyphenyl)-7H- pyrrolo[2,3-d]pyrimidine-6-carboxylate (10). Also the reaction of compound (5) with piperidine, and morpholine, gave the piperidino- and morphilino- derivatives (7) and (8) respectively. \ The compound (10) was used as key intermediates in the synthesis of other new pyrrolo[2,3-d]pyrimidine derivatives (11-13), pyrimido[4\\5\\4,5]pyrrolo[2,3-d]pyrimidines (14-17a-c) and triazolopyrrolopyrimidines (18, 19) by reaction with different reagents . Eight compounds were selected and screened in vitro for their
