On October 17, 2000, Pamukcu, Rifat; Piazza, Gary A. published a patent.Recommanded Product: 2,4-Dichloro-5,6-dimethylthieno[2,3-d]pyrimidine The title of the patent was Preparation of thienopyrimidines for inhibiting neoplastic cell growth. And the patent contained the following:
Title compounds [I; R = (un)substituted phenyl(alkyl); R1,R2 = H, halo, alkyl, alkoxy, etc.; R1R2 = alkylene; R3 = (un)substituted cycloalkyl, -heterocyclyl, -(hetero)aryl, etc.] were prepared for inhibiting neoplastic cell growth (no data). Thus, 2,4-dichloro-6-methylthieno[2,3-d]pyrimidine was aminated by 3,4-methylenedioxybenzylamine to give I (R = 3,4-methylenedioxybenzyl, R1 = Me, R2 = H)(II; R3 = Cl) which was condensed with Et piperidine-4-carboxylate to give II (R3 = 4-ethoxycarbonylpiperidino). The experimental process involved the reaction of 2,4-Dichloro-5,6-dimethylthieno[2,3-d]pyrimidine(cas: 42518-42-3).Recommanded Product: 2,4-Dichloro-5,6-dimethylthieno[2,3-d]pyrimidine
