4a-(m-Methoxyphenyl)-1,3-diketo-1,2,3,4,4a,5,6,7-octahydroisoquinoline → 4a-(m-Methoxyphenyl)-1,3-diketo-trans-decahydroisoquinoline

Participants

Reaction Steps

A solution of 4a-(m-methoxyphenyl)-1,3-diketo-1,2,3,4,4a,5,6,7-octahydroisoquinoline (6.0 g) in 250 ml of glacial acetic acid was treated with 1 g of 5% palladium on carbon and the mixture hydrogenated under 40 psi of hydrogen for 24 hours in a Parr shaker. The catalyst was then filtered off and the filtrate evaporated. The residual 4a-(m-methoxyphenyl)-1,3-diketo-trans-decahydroisoquinoline was recrystallized from ethanol, m.p. 189-190.
