실험 절차
To a solution of 1.80 g. (0.006 mole) 3-phenyl-5,8-dihydro-6,6,8-trimethyl-5,8-ethano-6H-pyrano[4,3-e]-as-triazine-4-oxide and 1.50 g. (0.018 mole) cyclohexene in 30 ml. absolute ethanol there is added 60 mg. 10% palladium on charcoal. The resulting mixture is refluxed under a nitrogen atmosphere for 18 hours. The catalyst is then removed by filtration and the filtrate evaporated to give 3-phenyl-5,8-dihydro-6,6,8-trimethyl-5,8-ethano-6H-pyrano[4,3-e]-as-triazine; m.p. 180° to 189° C.
