The compound characterized by the structural Formula I: ##STR1## is therapeutically useful as an anti-hypertensive agent. A process for the preparation of the compound having Formula I and their synthetic intermediates is described. One of the synthetic intermediates is the compound characterized by the structural Formula: ##STR2## which is also therapeutically useful as an anti-hypertensive agent.

The 13C NMR assignment of indoles and 5‐methoxyindoles substituted at position 3, and some of their N‐carboalkoxy derivatives, was achieved from one‐ and two‐dimensional NMR experiments. Substituent chemical shifts and 1 J(CH) values were evaluated. The dynamic processes of N‐carboalkoxyindoles and N‐carboalkoxyindoline observed by high‐field 1H NMR show the existence of two preferred rotamers around
