Versuchsvorschrift

To a solution of 0.271 grams (0.001 mole) 5,7-dihydro-5,5,7,7-tetramethyl-3-phenylfuro-[3,4-e]-as-triazine-4-oxide and 0.246 grams (0.003 mole) cyclohexene in 4 ml. absolute ethanol is added 100 milligrams of 10% palladium on charcoal and the resulting mixture is refluxed under an atmosphere of nitrogen for 18 hours. The catalyst is removed by filtration and the filtrate evaporated to dryness. The residue is recrystallized from ether/hexane to give 5,7-dihydro-5,5,7,7-tetramethyl-3-phenylfuro[ 3,4-e]-as-triazine, m.p. 90°-91° C.
