On October 6, 2008, Harris, Craig S.; Germain, Herve; Pasquet, Georges published an article.Quality Control of tert-Butyl 7-(2-hydroxyethyl)-3,4-dihydro-1,8-naphthyridine-1(2H)-carboxylate The title of the article was Facile preparation of thiophene C2-ethers using the Mitsunobu reaction. And the article contained the following:
The preparation of thiophene ethers generally requires forcing conditions thus limiting the choice of alkyl substituent. Herein, we report the first successful generally applicable conditions for the selective O-alkylation of 2(5H)-thiophenone. The experimental process involved the reaction of tert-Butyl 7-(2-hydroxyethyl)-3,4-dihydro-1,8-naphthyridine-1(2H)-carboxylate(cas: 445490-78-8).Quality Control of tert-Butyl 7-(2-hydroxyethyl)-3,4-dihydro-1,8-naphthyridine-1(2H)-carboxylate
