absorption, distribution, metabolism and eliminationstudies of the compound in animals and for use as mass spectral internal standards in support of bioanalytical assays, respectively. [14C]PD0198961 was prepared from [14C]CuCN in four radiosynthetic steps in an overall yield of 48% with a radiochemical purity of >99%. The cyanation reaction of an aromatic bromide with inorganic [14C]cyanide as a key
