Zusammenfassung:Compounds of the formula wherein R1 is hydrogen, halogen or cyano; R2 is fluorine, cyano, trifluoromethyl, nitro or alkyl of 1 to 4 carbon atoms; R3 is alkoxy of 1 to 5 carbon atoms, alkenyloxy of 2 to 5 carbon atoms, aryloxy of 6 to 10 carbon atoms, aralkoxy of 7 to 11 carbon atoms, or -NR5R6, where R5 and R6 are each hydrogen, alkyl of 1 to 5 carbon atoms, alkenyl of 2 to 5 carbon atoms, aryl of 6 to 10 carbon atoms or aralkyl of 7 to 11 carbon atoms; and R4 is cycloalkyl of 3 to 5 carbon atoms or alkyl of 3 to 5 carbon atoms; and non-toxic, pharmacologically acceptable acid addition salt thereof. The compounds as well as the salts are useful as analgesics, uterospasmolytics and antiasthmatics.
