1 The ‘modified KELLER-reaction’ has been applied to (a) lysergic acid derivatives, (b) Harmala-alkaloids and (c) phenothiazines. It is shown that: (a) Most of the lysergic acid derivatives (the mono- and disubstituted compounds as well as the ring-substituted N-acetyl-lysergic acid diethylamide) are characterized by absorption curves clearly distinct from those of the simpler indoles reported in a former publication.
