Condensation of 2-cyanomethyl benzaldehydes 1 with 2 (ammonia, primary or secondary amines) carried out in the presence of a catalytic amount of trifluoroacetic acid, afforded 3aminoisoquinolines 3. In the case of primary amines azomethines 4 were formed at first, they dissociated and subsequently yielded 3 in a rather slow process.
