The mixture of 5 g of slow moving 1-(2-isopropylaminopropyl)-9-methoxy-3,4,5,5a,6,7-hexahydro-2H-naphth[1,2-d]azepin-2-one and 14.75 ml of liquified ethylene oxide in 100 ml of absolute ethanol is stirred in a sealed pressure tube at room temperature for two days. The reaction mixture is recharged with an additional 14.75 ml portion of ethylene oxide and stirred for four additional days at room temperature. It is evaporated, the residue slurried in diethyl ether, collected by filtration and recrystallized from ethyl acetate to yield the 1-[2-(N-isopropyl-N-2-hydroxyethylamino)-propyl]-9-methoxy-3,4,5,5a,6,7-hexahydro-2H-naphth[1,2-d]azepin-2-one, RR racemate melting at 147°-149°.
