Abstract
Novel indole derivatives of the general formula I can be obtained by reacting, directly or indirectly, N,N-dimethyl-3-indolemethylamine with a Schiff base of the general formula II, ##STR1## in which R.sup.1 is cyano or methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl or butoxycarbonyl, and .phi. is phenyl. The successive hydrolysis of the indole derivatives of the general formula I in the presence of an acid and of a base gives tryptophane.
