    摘要: Antiviral activity against respiratory syncytial virus has been found in some substituted 6-aminopyrimidines having the formula: ##STR1## wherein R.sup.1 is lower alkyl, preferably methyl or t-butyl, R.sup.2 is halogen or cyano, and R.sup.3 is C.sub.1 -C.sub.6 alkyl or --(CH.sub.2).sub.n R.sup.4 where n is 1 or 2 and R.sup.4 is phenyl, phenyl substituted by lower alkoxy, lower alkyleneoxy, bromo, or 3,4-methylenedioxy; 3 or 4-pyridinyl, pyridinyl substituted by cyano or bromo, thienyl, or di-(C.sub.1 -C.sub.6 alkyl)amino.
