Abstract
A method for the preparation of substituted gramines, viz., 3-(α-aminobenzyl)-2-carbethoxyindoles, by alkylation of amines with 3-(α-halobenzyl)-2-carbethoxyindoles was developed. Ammonia, primary and secondary amines, and pyridine were used. Anhydronium bases, viz., 3-indolidenephenylmethanes, were isolated and characterized.
