2-(2,6-dimethyl-3,5-diethoxycarbonyl-1,4-dihydropyridine-4-carboxamide) glutaric acid of formula I and its disodium salt of formula II ##STR1## Said acid is obtained from glutaminic acid and dimethyl 3,5-diethoxycarbonyl-1,4-dihydroisonicotic acid.For obtaining disodium salt, said acid is reacted with a caustic soda solution.These compounds possess antiarrhythmic activity.
摘要:
2,6-Dimethyl-1,4-dihydropyridine-3,5-dicarboxylic acid esters of the general formula: ##STR1## wherein R is a substituted alkyl or terpenyl. A method for preparing said esters comprises reacting esters of acetoacetic acid of the general formula: CH.sub.3 COCH.sub.2 COOR, wherein R is a substituted alkyl or terpenyl, with hexamethylenetetramine in the presence of ammonium acetate in ethanol at its boiling temperature; said esters of acetoacetic acid of the above general formula, hexamethylenetetramine and ammonium acetate can be used in stoichiometric proportions.
