a solution of 3p-methoxy-17a-meth.ylandrost-5-en-17p-o115 (1.0 g.) in 95% ethanol (35 ml.) was added 5 7 , palladium-on-carbon (0.1 g.). The mixture was hydrogenated at atmospheric pressure and room temperat~re.1~ Hydrogen uptake was complete after 3 hr. and the catalyst was removed by filtration and washed with ethanol. The solvent was removed from the filtrate and (15) 11. N. Huffnian and J. u'. Sadler, J . Org. Chem.. 18, 924 (1953). the residue crystallized from 95% ethanol. This gave VI1 (0.8 g.), m.p. 178-179', and a second crop (0.15 g.), m.p. 176-178". Recrystallization from methanol-water atlorded an analytical sample, m.p. [180][181]
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
