14 CIPelrinone (1,4-d~Qydro-2-methyl-4-0~0-6[ (3-pyridinylrnethy1)amino]-5-pyrimidine-[ C]-carbonitrile hydrochloride; AY-28,768 hydrochloride) , a potent 'notropic agent, was prepared by reacting chloroacetic acid with [ C]sodium cyanide to give the labelled cyanoacetic acid. compound, condensed with acetamidine hydrochloride, coupled with 3-aminomethylpyri~ine, and treated with methanolic hydrochloric acid. Two batches of [ C] firinone were produced, giving a combined overall yield of 15.6% from f C]sodium cyanide (sp. act. 66.2 r 1.5 and 64.2 f 1.9 pCi/mg; 98.8 and 98.0% radiochemical purity, respectively).
