    摘要: Compounds of the formula ##STR1## wherein: Y is alkylene of 3 to 9 carbon atoms;R.sub.1 is lower-alkyl, lower-alkoxy-(C.sub.1-3 -alkyl), lower-alkoxycarbonyl, cyclopropyl or trifluoromethyl;R.sub.2 and R.sub.3 independently are hydrogen, lower-alkyl, halogen, lower-alkoxy, nitro, trifluoromethyl or hydroxy; andR.sub.4 is hydrogen or lower-alkyl; where lower-alkyl and lower-alkoxy, each occurrence, have from 1-5 carbon atoms;with the proviso that when R.sub.1 is lower-alkyl, at least one of R.sub.2 and R.sub.3 is hydroxy; or pharmaceutically acceptable acid-addition salts thereof are useful as antiviral agents, particularly against picornaviruses, including numerous strains of rhinovirus.
