In 1911, A. Pictet and T. Spengler condensed phenylethylamine and dimethoxymethane in concentrated hydrochloric acid to give 1,2,3,4-tetrahydroisoquinoline. They also observed a similar reaction when tyrosine and phenylalanine were treated in the same way.
In 1893, C. Pomeranz and P. Fritsch independently described a new synthesis of isoquinoline. This was prepared by heating a benzalaminoacetal generated through the condensation of benzaldehyde and 2,2-diethoxyethylamine in concentrated sulfuric acid.
