Reaction Steps

A solution of 6.30 g (0.024 mol) of ethyl rac-1,2,3,4-tetrahydro-5-methoxy-2-oxo-1-napthylacetate in 100 ml of toluene was treated with 3.1 ml (0.024 mol) of 4-(2-aminoethyl)morpholine, whereupon the mixture was boiled on a water separator for 20 hours. After concentration the residue was hydrogenated with 1 g of Raney-nickel in 100 ml of ethanol at 120° and 180 bar. The product was chromatographed over silica gel with methylene chloride/methanol (9:1). There were obtained 6.80 g (86%) of oily rac-cis-1,3,3a, 4,5,9b-hexahydro-6-methoxy-3-(2-morpholinoethyl)-2H-benzo[e]indol-2-one.
