Abstract
The compounds having Formula I, ##STR1## wherein X is a fluorine or methoxy group, and R is a hydrogen or methyl group, such that R is hydrogen only when X is fluorine are novel. The compounds having Formula I and their acid addition salts are useful for the treatment of hypertension. Processes for the preparation of the compounds having Formula I and useful intermediates are described.
