Compounds of the formula
wherein:
Y is alkylene of 3 to 9 carbon atoms;
R₁ is lower-alkyl, lower-alkoxy-(C₁₋₃-alkyl), lower-alkoxycarbonyl, cyclopropyl or trifluoromethyl;
R₂ and R₃ independently are hydrogen, lower-alkyl, halogen, lower-alkoxy, nitro, trifluoromethyl or hydroxy; and
R₄ is hydrogen or lower-alkyl; where lower-alkyl and lower-alkoxy, each occurrence, have from 1-5 carbon atoms;
with the proviso that when R₁ is lower-alkyl, at least one of R₂ and R₃ is hydroxy; or pharmaceutically acceptable acid-addition salts thereof,
are useful as antiviral agents, particularly against picornaviruses, including numerous strains of rhinovirus.
