Reaction Steps

The (5α,20R)-4-benzoyl-3-oxopregnane-20-carboxaldehyde (436 mg, 1.0 mmole) in tetrahydrofuran:methanol (2.0 ml, 1:1) is mixed with sodium borohydride (9.5 mg, 0.25 mmole) at 0° C. for 1 hours. The mixture is then diluted with ether and washed with 0.5 N hydrochloric acid and brine and then dried and the solvent is evaporated to leave, as a resiue, (5α,20R)-4-benzoyl-21-hydroxy-20 -methylpregnan-3-one.
