After cooling to RT, the mixture was diluted with water (20 mL) and acidified with formic acid to pH 6. The mixture was then extracted with ethyl acetate (30 mL×5) and the combined organics concentrated. The residue was passed through a phase separator (C18 cartridge) eluting with water (20 mL×3) and MeOH (20 mL×5) and the combined methanolic fractions concentrated and dried, to give the title compound (388 mg). LCMS (A) m/z: 504 [M+1]+, Rt 1.17 min (acidic).

Procedure:
3α-Hydroxy-5α-pregnane-11,20-dione (1 g.) in stirred methanol (7 ml.) at 30° was treated with acetyl chloride (1 drop). After two minutes bromine (0.19 ml.) in methanol (4.5 ml.) was added dropwise. The solution being allowed to decolourise between the addition of each drop. The resulting clear solution was poured into chloroform (100 ml.), washed with water (3 × 50 ml.) dried (Na2SO4) and evaporated to a white froth (1.40 g.). Preparative t.l.c. afforded title compound (715 mg.) which crystallised from chloroform/ether as clusters of colourless needles, m.p. 160°-163°; [α]D + 109° (c 0.82).
