In 1975,Bulletin de la Societe Chimique de France included an article by Rene, Loic; Buisson, Jean P.; Royer, Rene. Application In Synthesis of Ethyl 6-methoxybenzofuran-2-carboxylate. The article was titled 《Reactions induced by pyridinium halides. XX. First examples of dealkylation by pyridinium hydrochloride in quinoline》. The information in the text is summarized as follows:
Benzofuranols I-VI (R = R1 = H, R2 = H, Me) were prepared in improved yields by demethylating I-VI (R1 = Me) with pyridine-HCl in quinoline. I-VI (R1 = Me) were prepared by formylating coumarilic acid esters, hydrolyzing I-VI (R = CO2Me, CO2Et, R1 = Me), and decarboxylating I-VI (R = CO2H). In addition to this study using Ethyl 6-methoxybenzofuran-2-carboxylate, there are many other studies that have used Ethyl 6-methoxybenzofuran-2-carboxylate(cas: 50551-57-0Application In Synthesis of Ethyl 6-methoxybenzofuran-2-carboxylate) was used in this study.
Ethyl 6-methoxybenzofuran-2-carboxylate(cas: 50551-57-0) belongs to benzofurans.Application In Synthesis of Ethyl 6-methoxybenzofuran-2-carboxylateBenzofurans containing one furan ring that have been implicated as psychoactive recreational drugs include 6-(2-aminopropyl)benzofuran (6-APB), 5-(2-aminopropyl)benzofuran (5-APB), 5-(2-ethylaminopropyl)benzofuran (5-EAPB), and 5-methylaminopropylbenzofuran (5-MAPB).
