Abstract
Procedure for obtaining fluorene derivatives of formula IIIa, **(See formula)** in which R'means an isopropyl, secondary butyl, tertiary butyl or 3-phenylpropyl radical, characterized in that 4-hydroxy-fluoren-9-one is reacted in an alkaline medium or in ammonia with epichlorohydrin or epibromhydrin, preferably with 1 to 5 equivalents of epichlorohydrin or epibromhydrin, and the resulting reaction product is heated with an amine of formula VI, **(See formula)** wherein R1 has the meaning indicated above, at room temperature or at an elevated temperature, for example 50 °.
