## Abstract The synthesis of a new radioligand, which binds with high selectivity and affinity (K~D~ = 7.4 nM) to the GABAβB receptor, is described. A WittigβHorner approach was employed to prepare an unsaturated protected intermediate (6), suitable for tritiation and deprotection.
A simple and effective separation of cyclic adenosine-3',5'-monophosphate (CAMP) and its butyryl-substituted analogues using partition chromatography on columns of Sephadex gel in isopropanol/0.5M ammonium acetate (4:l) is described. The technique is suitable for preparative separations as demonstra
