Chen, Chen; Sun, Chengyu; Xu, Shan; Tu, Yuanbiao; Zheng, Pengwu; Zhu, Wufu published the artcile< Synthesis of one novel thieno[2,3-D]pyrimidine derivative bearing a sulfonylurea moiety>, Synthetic Route of 18740-39-1, the main research area is thieno pyrimidine sulfonylurea.
A novel thieno[2,3-d]pyrimidine compound (1) bearing a sulfonylurea moiety was synthesized from Me 2-aminothiophene-3-carboxylate (2) through five steps including cyclization, chlorination, substitution with morpholine and piperazine, amidation and its structure was confirmed by 1H NMR and MS spectrum. The total yield of the five steps was 16.2% (calculated from Me 2-aminothiophene-3-carboxylate).
Advanced Materials Research (Durnten-Zurich, Switzerland) published new progress about Amidation. 18740-39-1 belongs to class pyrimidines, and the molecular formula is C6H2Cl2N2S, Synthetic Route of 18740-39-1.
