Cholestan-3-one and cholestane-3,6-dione were allowed to react under the conditions of the Mannich reaction with paraformaldehyde and amine hydrochlorides. The products obtained proved to be methylene-bis-ketones, and were formulated as di(2,2′-3-oxocholestanyl)methane and di(4,4′-3,6-dioxocholestanyl)methane respectively.
