Abstract

PROCEDURE FOR THE OBTAINING OF PIRROL DERIVATIVES FROM FORMULA (I), AND THEIR SALTS, WITH ORGANIC OR MINERAL ACIDS, IN WHICH R1 IS HYDROGEN OR A RADICAL LOWER ALKYL, PHENYL OR PIRIDYL-2; R2 IS HYDROGEN OR A RADICAL LOWER ALKYL; R3 AND R4 MAY BE A RADICAL LOWER ALKYL OR CYCLLOALKYL, OR THE GROUP -NR3R4 IS THE RADICAL OF A CYCLIC AMINE, AND IS VALUE 2 OR 3. IT IS BASED ON THE REACTION OF A COMPOUND OF FORMULA (II), IN WHICH R1 IT IS THE SAME AS ON THE FORMULA (I); AC IS AN ACID OR ACID-DERIVED GROUP, AND P IS A RADICAL OF FORMULA - (CH2) NNR3R4, IN WHICH R3, R4 AND N HAVE THE SAME MEANING AS IN FORMULA (I), WITH A DICETONE OF FORMULA (III), IN WHICH R2 IS THE SAME AS IN FORMULA (I) OR WITH DIMETOXI-2,5-TETRAHIDROFURANO. THE REACTION IS CARRIED OUT FOLLOWING CONVENTIONAL METHODS. (Machine-translation by Google Translate, not legally binding)
