A convenient synthesis of 1-(1,2,3,6-tetrahydro-1-methyl-4-pyridinyl)ethanone, isoarecolone, starting with 4-acetylpyridine is presented. 4-Acetylpyridine was protected as the ketal followed by reaction with iodomethane to give the quaterary salt. The quaterary salt was reduced with sodium borohydride followed by deprotection to give isoarecolone in 80% overall yield.

to 2.03 microM for olivacine) and an opposite effect is observed for hydroxylation at position 7 (ID50 = 12.8 microM). On the other hand, hydroxylation at position 9 has no effect on the in vivo antitumor activity against L1210. This might be related to the oxidative and conjugative metabolic pathways that play an important role in antitumor activity and deactivation of olivacine and its hydroxy metabolites
