Abstract

Process for the preparation of isoquinolines of the formula <IMAGE> in which R is methyl or benzyl and R' is phenyl, p-hydroxyphenyl or p-methoxyphenyl, characterised in that a solution of an enamine of the formula <IMAGE> in which R and R' have the above meaning, is reacted in a hydrocarbon with an anhydrous solution of p-toluenesulphonic acid in toluene or xylene at elevated temperature.
