“…The organic phase was dried over magnesium sulfate, filtered, and evaporated to dryness. The iodo derivative 6 was purified by preparative HPLC (MeOH/H20 90:10, tR = 44 min) and crystallized from ether as a white powder (24 mg, 75%): mp 65-66 °C; TLC, £,0.53; UV (EtOH) 281, 287 min; NMR (CDClg) 0.78 (s, 3 H, I8-CH3), 0.99-2.35 (br m, 32 H, chain and steroid), 2.67-2.91 (m, 2 H, 6-CH2), 3.18 (t, 2 H, J = 7.0 Hz, CH2I), 3.75 (t, lH,</= 8.2 Hz, 17-H), 4.62 (s, 1 H, ArOH), 6.55 (d, 1 H, J = 2.8 Hz, 4-H), 6.63 (dd, 1 H, J = 8.4, 2.9 Hz, 2-H), 7.15 (d, 1 H, J = 8.5 Hz, 1-H); MS m/z 552 (27, M+), 424 (1), 271 (1), 253 (15), 171 (22), 157 (100), 145 (47).
