Abstract
A PROCEDURE FOR THE PREPARATION OF IMIDAZO-DIACEPINA DERIVATIVES. IT CONSISTS OF TRANS-ESTERIFYING A COMPOUND OF GENERAL FORMULA (I) TO OBTAIN THE COMPOUND (II) WHICH, IF DESIRED, IS TRANSFORMED IN THE PHARMACEUTICALLY ACCEPTABLE ACID ADDITION SALT; R2 IS HYDROGEN AND R3 IS HYDROGEN OR LOWER ALKYL, WHILE R2 AND R3 TOGETHER REPRESENT TRIMYTILENE OR PROPYLENE; R4 IS METHYL, ETHYL, ISOPROPYL OR2-HYDROXY-ETHYL. TRANS-ESTERIFICATION TAKES PLACE BY REACTING COMPOUND (I) WITH AN ALCOHOL, SUCH AS METHANOL, ETHANOL, ISIPROPANOL OR ETHYLENGLYCOL AT ROOM TEMPERATURE OR WHILE HEATING BETWEEN 25 AND 150 DEGREES. SUCH REACTION TAKES PLACE PREFERABLY IN THE PRESENCE OF A BASE. (Machine-translation by Google Translate, not legally binding)
