Butler, Jerry L. et al. published their research in Transactions of the Kentucky Academy of Science in 1977 | CAS: 23707-37-1

Isoquinolin-7-amine (cas: 23707-37-1) belongs to isoquinoline derivatives. Quinoline is a catabolite of tryptophan, the basic structure of some antihypertensive drugs, such as the peripheral vasodilators prazosin and doxazosin. The Pomeranz–Fritsch reaction provides a method for the preparation of isoquinoline. This reaction uses a benzaldehyde and aminoacetoaldehyde diethyl acetal, which in an acid medium react to form isoquinoline.COA of Formula: C9H8N2

Preparation of monobromoisoquinolines was written by Butler, Jerry L.;Bayer, Forrest L.;Gordon, Marshall. And the article was included in Transactions of the Kentucky Academy of Science in 1977.COA of Formula: C9H8N2 This article mentions the following:

1-, 3-, 4-, 5-, 6-, 7-, And 8-bromoisoquinolines were prepared by several methods. Thus, p-BrC6H4CHO was condensed with H2NCH2CH(OEt)2 and the benzaliminoacetal cyclized to give 6-bromoisoquinoline. 1-Bromoisoquinoline was prepared by treating 1-isoquinolinol with PBr3. In the experiment, the researchers used many compounds, for example, Isoquinolin-7-amine (cas: 23707-37-1COA of Formula: C9H8N2).
