Procedure

7α-Hydroxymethylandrostane-3,17-dione (II-bx) was prepared in 85% yield from 3,3:17,17-bis(ethylendioxy)-7α-hydroxymethylandrostane by the procedure described above for the preparation of 6α-cyanoandrostane-3,17-dione (II-ac, Prepn. 3). The combined organic extracts were washed with H2O, dried over Na2SO4 and evaporated to dryness. 1H-NMR (300 MHz, DMSO-d6, ppm from TMS): δ 4.30 (t, 1H), 3.48 (m, 2H), 2.46-0.95 (m, 21H), 1.00 (s, 3H), 0.78 (s, 3H)
