Reaction Steps

A solution of citric acid (1.77 g) in hot ethanol (10 ml) was added to a solution of (-) -1-[1-(3,4-dichlorophenyl)cyclobutyl]-2-[3-(dimethylamino)-propylthio]ethanol (3.42 g) in ether (30 ml), and the mixture was stored at 4° C. for 18 hours. The resulting solid was collected by filtration, washed with ether and dried in vacuo at ambient temperature for 24 hours, to give (-)-1-[1-(3,4-dichlorophenyl)cyclobutyl]-2-[3-(dimethylamino)propylthio]ethanol citrate as a white solid (3.9 g) , m.p. 109°-115° C., [α]rtD =-10.17° (C=1; methanol) .
