This invention relates to compounds of the formula ##STR1## where R.sub.1 and R.sub.2 are independently hydrogen or loweralkyl or R.sub.1 and R.sub.2 taken together with the carbon atom to which they are attached form a spiro-fused cycloalkane of 5 to 8 carbons; R.sub.3 and R.sub.4 are independently hydrogen or loweralkyl or R.sub.3 and R.sub.4 taken together with the carbon atom to which they are attached form a spiro-fused cycloalkane of 5 to 8 carbons; R.sub.5 and R.sub.6 taken together with the nitrogen atom to which they are attached are ##STR2## where X in each occurrence is independently hydrogen, halogen, loweralkyl, hydroxy, nitro, amino, cyano, trifluoromethyl or methoxy; and m is 0, 1 or 2; the pharmaceutically acceptable acid addition salts thereof and where applicable the optical and geometrical isomers and racemic mixtures thereof. The compounds of this invention are useful as analgesic and antihypertensive agents.
