The antitumoragent 2-formyl-4-(m-amino)phenylpyridine thiosemicarbazone (4-APPT) has been synthesized by a new route to give significantly better overall yields than previously reported. 4-Phenyl-2-picoline was formed by methylation o4-phenylpyridine with CH3Li which upon nitration produced a mixture of o-, m-, and p-nitro-substituted derivatives. These isomers were separated by the solubility differences
