| 摘要 |
The invention relates to N-(2-hydroxyethyl)-p-nitrogenousphenacyl-8-theophyllinehydrazone, as well as to a process for preparing the same. The process consists in reacting -bromine-p-nitrogenouspneacyl-8-theopyllinehydrazone with nitrogenous monoethanole amine nitrate in dimethylformamide medium, in the presence of anhydrous potassium carbonate. The derivative is a heavy brown-coloured compound with a melting point of 172...174 degree C, soluble in organic solvents, non-soluble in water, with antihipertensive and coronary-dillating properties
