Abstract

Procedure for the preparation of a fluorane compound, expressed by the general formula I **(See formula)** where R1 and R2 each represent a lower alkyl group, having no more than 5 carbon atoms, R3 represents a hydrogen atom, a lower alkyl group, having no more than 5 carbon atoms or a benzyl group, and represents a aryl group, characterized in that it comprises the operation of condensing an ortho- (4-dialkylamino-2-hydrosibenzoyl) benzoic acid, expressed by the general formula II **(See formula)** wherein R1 and R2 are the same as defined above, and a para-arylamino phenol, expressed by the general formula III **(See formula)** where R3 and R4 are the same as defined above.
