Abstract

Compounds of formula: <IMAGE> in which R3 represents a C1-C5 alkyl are prepared by decarboxylation of a corresponding alkyl ester carrying a carboxyl in position 1, followed by a nitration. The compound IB can be reduced to an amino ester (IC), can be hydrolysed to the carboxylic acid (IE) or can be reduced and then hydrolysed. The amine compound IC can be converted by acylation into the acylamino compound, and the carboxylic acid IE can be esterified or converted to the amide. The compounds mentioned above and their salts have antiallergic and bronchodilatory properties; they can be used, especially, in the treatment of allergic asthma.
