Notes:
The synthesis of crystalline 1-(2-pyrimidyl)-4-(3, 4-methylenedioxybenzyl)-piperazin methanesulfonate (ET 495) labelled with 14C fixed on the piperazine nitrogen N(4) has been realized in five steps from barium carbonate 14C; Specific activity of the final product: 32,8 mCi/mmol (110 m̈Ci/mg); radiochemical purity: around 99%. The mass spectrum of the labelled compound is in agreement with the chemical structure and the labelling position expected.
