실험 절차

1.6 g of 5,10-dihydro-pyrido[3,4-g]isoquinoline and 0.32 g of palladium-on-charcoal was dispersed and mixed in 100 cc of dimethoxyethyl ether, and refluxed for 15 hours under argon atmosphere. After the filtration of palladium-on-charcoal and solvent was evaporated to obtain crude pyrido[3,4-g]isoquinoline. The product was purified by preparative liquid chromatography (gel; R-055-15, S16SIL, YMC Ltd., developing solvent; ethyl alcohol/benzene=3/7). The yield of the compound was 1.3 g (95%) and its m.p. was 174° C. The compound was identified as pyrido [3,4-g]isoquinoline based upon the following elemental analysis.
