Participants

Reaction Steps

30g of 6-(4-aminophenyl)-8,9-dimethoxy-2-methyl-1,2,3,4,4a,10b-hexahydro-benzo[c][1,6]naphthyridine and 6,0 g of phenylacetic acid chloride are heated to the boil under reflux in 70 ml of acetonitrile for 7 hours. After working up in a manner analogous to that described in Example 31, and upon adding dilute hydrochloric acid in ethanol to the crude product, the dihydrochloride form of the title compound slowly crystallizes (melting point 240°-245°).
