Procedure
Prepared in 33% yield as described in Example 1 starting from 6α-methoxymethylandrostane-3,17-dione (II-ap, Prepn. 16) and 2-aminoethoxyamine dihydrochloride. The crude product was crystallized from Et2O/EtOAc. 1H-NMR (300 MHz, DMSO-d6, ppm from TMS): δ 7.82 (bb, 3H), 4.06 (m, 2H), 3.22 (m, 2H), 3.20 (s, 3H), 3.05 (m, 1H), 3.02 (m, 2H), 2.45-0.60 (m, 20H), 0.89 (s, 3H), 0.78 (s, 3H).
