Reaction Steps

In methanol (20 ml) is dissolved 1-(6,7-dimethoxy-3,4-dihydro-3-naphthoyl)-4-(3,4,5-trimethoxybenzoyl)piperazine (0.6 g). The solution is subjected to catalytic reduction in a stream of hydrogen in the presence of a 10% palladium-carbon (0.3 g). The reaction mixture is filtered off. The filtrate is concentrated under reduced pressure. To the concentrate is added ether, and the mixture is stirred. The resulting colorless powder is collected by filtration to afford 6,7-dimethoxy-1,2,3,4-tetrahydro-2-naphthoyl)-4-(3,4,5-trimethoxybenzoyl)piperazine (0.5 g).
