โฆ Synopsis
Ester Methylene-3 H] CEP-2563 (9) was synthesized by the tritiation of precursor 6 with NaB 3 H 4 followed by esterification with BOC-Lys(BOC)-b-Ala-OH and deprotection.

The octahydroindenone intermediate was tritium labeled using T 2 O isotope exchange labeling, and then elaborated to the vitamin D derivative RO275646. Though this method of labeling was expected to give the minor isomer, it was the shortest and most convenient route to the high specific activity me
Since its introduction to medicine several years ago, diphenylhydantoin (DPH) has been widely used in the treatment of epilespy, both in adults and children.( 2) The effects of the drug is well correlated with the plasma levels. high levels have adverse effects. ( 3 )
## Abstract The possibilities of tritium labelling of tofizopam (**1**) at high specific activity were investigated. Two methods, one by isotopic exchange, and one by catalysed halogenโtritium replacement were developed. The latter was found to be more rational, and **1** specifically labelled with
## Abstract Tritium labelled amitriptyline (__1__) of high specific activity was prepared. The tritium was incorporated by catalysed isotope exchange into the precursor dibenzosuberone, which had been previously converted into a cyclic ketal, in order to protect the oxoโgroup against reduction. It
