N-(9H-Xanthen-9-yl)succinimide (1) is prepared by the reaction of xanthene with N-bromosuccinimide. Hydrolysis of 1 with 5% NaOH yields 3-[(9H-xanthen-9-yl)inocarbonyl]propionic acid (3a). The corresponding methyl ester 3c is obtained from 3a by the action of diazomethane. The butanol derivative 4a
