Calculate Digit Verification of CAS Registry Number 120616-39:
(8*1)+(7*2)+(6*0)+(5*6)+(4*1)+(3*6)+(2*3)+(1*9)=89

Synthesis of N(3-dimethylaminopropyl)-6-substituted Naphthothiophene-4-carboxamides

Ming, Yang,Boykin, David W.

, p. 1729 - 1731 (2007/10/02)

A series of N-(3-dimethylaminopropyl)-6-substituted naphthothiophenes-4-carboxamides have been synthesized. 6-Substituted naphthothiophene-4-carboxylic acids were obtained upon oxidative-photocyclization of α-(2-thienyl)-β-arylacrylic acid.The naphthothiophene carboxylic acids were converted to the corresponding amides through their chlorides or, in one case, by use of 1,1-carbonyldiimidazole coupling of the amine and the acid.
