Abstract
A process for the preparation of a salt, with a basic amino sugar or a basic amino acid, of a benzopyran derivative of the formula **(See formula)** where R1, R2, R3, R4, R5 and R7, which may be the same or different, individually represent hydrogen, hydroxyl, alkoxy, alkoxy substituted by phenyl, carboxylic acyl, amino, carboxylic acylamino, halogen or alcoholic alkenyl, provided that at least one of the groups R1, R2, R3 and R7 are other than hydrogen or hydroxyl, or an adjacent pair of groups R1, R2, R3 and R7, or represent hydroxyl and a 3- (N, N-dialkoxylamino) acryloyl radical, or together represent a chain -COCH = CH-O-, X represents a hydrocarbon chain of 2 to 10 carbon atoms, optionally substituted by a hydroxyl group, and E represents a carboxyl or tetrazole group, comprising reacting a compound of formula I with a basic amino acid or a basic amino sugar.
