    摘要: The imidazoline 4-(3,4-dichlorophenyl)-2-(methylamino)-2imidazoline and non-toxic pharmaceutically acceptable acid addition salts thereof are useful as antihypertensive agents. Displacement of the methyl mercapto grouping from 2-methylthio-4(3,4-dichlorophenyl)-2-imidazoline with methylamine provides the imidazoline of the present invention.
