Abstract

^11^C‐Methyl labelled 1,1′‐dimethyl‐4,4′‐dipyridinium diiodide has been prepared by reaction of ^11^C‐iodomethane with 4,4′‐dipyridyl dihydrate. Radiochemical analysis of the product was by electrophoresis. The ^11^C‐iodomethane precursor was prepared rapidly from cyclotron produced ^11^CO~2~ by reduction to methanol with lithium aluminium hydride followed by treatment with hydriodic acid.

## Abstract Carbon‐14 labeled 3,5‐dihydro‐5‐methyl‐1(2H)‐isoquinolinone, a potent inhibitor of poly(ADP‐ribose) polymerase (ADPRP) was prepared from 1‐bromo‐2‐methylbenzene in 7.8 % overall yield. The C‐14 label was introduced from Ba^14^CO~3~ via metal‐halogen exchange and carboxylation reactions.
