A four-step synthesis of 5-carboxamidopyrrolo[3,2-b]pyridine (3) from pyrrolo[3,2-b]pyridine (4) is described (45% overall yield). The one-step conversion of the N-oxide 6 of the pyrrolo[3,2-b]pyridine 5 leads to the 5-cyanopyrrolo[3,2-b]pyridine 7. The cyano group is hydrolyzed to afford the title compound 3, which is the 4-aza analog of the indole backbone in 5-carboxamidotryptamine, a potent agonist
5- carboxamidopyrrolo [3,2的四步合成b ]吡啶(3从吡咯并[3,2-)b ]吡啶(4)中描述了(45%总收率)。吡咯并[3,2- b ]吡啶5的N-氧化物6的一步转化导致5-氰基吡咯并[3,2 - b ]吡啶7。氰基水解得到标题化合物3。,它是5-羧酰胺基色胺(一种神经递质5-羟色胺的有效激动剂)中吲哚骨架的4-氮杂类似物。
