Compounds of the formula ##STR1## wherein R.sup.1 is a straight or branched chain alkynyl group containing from 3 to 9 carbon atoms, inclusive; R.sup.2 is hydrogen, (lower)alkyl, halogen or hydroxymethyl; m is 1 or 2, and n is 2 or 3, provided that the sum of m and n is 3 or 4; X and Y each are independently hydrogen, nitro, cyano, --SO.sub.2 Ar or --COR.sup.3, provided that X and Y are not both hydrogen; R.sup.3 is (lower)alkyl, Ar, (lower)alkoxy, amino or (lower)alkylamino; and Ar is an optionally substituted phenyl group; and nontoxic pharmaceutically acceptable acid addition salts thereof, are potent anti-ulcer agents. Also disclosed are processes for their preparation and novel intermediates of the formulae ##STR2## in which R.sup.1, X, Y and n are as defined above and R.sup.5 is (lower)alkyl, phenylalkyl or phenyl containing 1 or 2 substituents independently selected from nitro, chloro and bromo.
