Abstract
The present invention provides a method to prepare an 18F-labelled tricyclic indole compound comprising a solid-phase extraction (SPE) purification step. This method is particularly suitable for carrying out the radiofluorination method on an automated synthesizer. In addition to the radiofluorination method, the present invention provides a cassette designed to carry out the method on an automated synthesizer.
