Reaction Steps
If colour bases which are obtained by coupling 4-anisidine to 1,3,3,5-tetramethyl-2-methylene-indoline, 5-chloro-1,3,3-trimethyl-2-methylene-indoline, 5-methoxy-1,3,3-trimethyl-2-methylene-indoline or 5-ethoxy-1,3,3-trimethyl-2-methylene-indoline are used instead of the colour base obtained from 4-anisidine and 1,3,3-trimethyl-2-methylene-indoline and the procedure is otherwise the same, valuable cationic hydrazone dyestuffs are likewise obtained.
