Procedure
To a stirred solution of 20-hydroxy-7β-methyl-5α-4-azapregnan-3-one (22.3 gms, 67 mmol, product of Step 10) in dry methylene chloride under nitrogen (110 mL) was added 4-methyl morpholine N-oxide (11.8 gms, 100 mmol) followed by 4 Å molecular sieves (33 gm). To this mixture was added tetrapropylammonium perruthenate (1.2 gm). After stirring at room temperature for 4 h, the reaction mixture was poured through pad of silica gel in a 300 mL sintered glass funnel which was subsequently eluted with 4:1 ethyl acetate/methylene chloride (5 L). The solvent was removed by rotoevaporation and the title compound recrystallized.
