Procedure
Prepared in 40% yield as described in Example 1 starting from 6-methyleneandrostane-3,17-dione (II-ah, Prepn. 8) and 2-aminoethoxyamine dihydrochloride. The crude product (1.65 g) was crystallized twice from EtOAc to give the title compound I-ai. H-NMR (300 MHz, DMSO-d6, ppm from TMS): δ 7.97 (bb, 3H), 4.81 (bs, 1H), 4.49 (bs, 1H), 4.08 (t, 2H), 3.10 (m, 1H), 3.02 (t, 2H), 2.45-0.85 (m, 19H), 0.77 (s, 3H), 0.75 (s, 3H).
