| 摘要 |
(2,3-Dihydro-2-benzo-furanylmethyl)guanidines and (2,3-dihydro-2-benzofuranylmethyl)-aminoguanidines, having anti-hypertensive activity, are prepared by reacting the corresponding respective 2,3-dihydro-2-benzo-furanylmethylamine or (2,3-dihydro-2-benzofuranylmethyl)hydrazine with a guanylating agent, e.g., 2-(lower-alkyl)-2-thiopseudourea or cyanamide. Preparation of various intermediates are given, e.g., 2,3-dihydro-2-benzofuranylmethyl halides, N-(2,3-dihydro-2-benzofuranylmethyl)phthalimides, 2,3-dihydro-2-benzofuranylmethylamines and (2,3-dihydro-2-benzofuranylmethyl)hydrazines.
