Abstract
Abstract Substituted amidines of the formula Ar(CH2)nC(N Z) NR where Ar is pyridyl, phenyl or substituted phenyl, n is O or an integer from 1 to 3, N Z is tertiary-amino and R is lower-alkyl, loweralkenyl or substituted lower-alkyl, having diuretic and antiinflammatory activity, are prepared by interacting an amide of the formula Ar(CH2)nCONHR with phosphorus pentachloride, and interacting the resulting imidyl chloride, Ar(CH2)nC(C1) NR with a secondary-amine, HN Z.
