المعالجة

  1. 1
    أخرىThe crude product (1/1 ratio of the E/Z isomers) was purified by flash chromatography (SiO2, CH2Cl2/MeOH/26% NH4OH 90/10/1)
  2. 2
    أخرىThe less polar fractions were evaporated to dryness

الإجراء التجريبي

The title compound I-dw was obtained following the procedure described in Example 100 and starting from 6-(E)-hydroxyiminoandrost-4-ene-3,17-dione (II-bw, Prepn. 63, 200 mg) and 3-(S)-pyrrolidinyloxyamine dihydrochloride (III-d, Prepn. 4) (110 mg). The crude product (1/1 ratio of the E/Z isomers) was purified by flash chromatography (SiO2, CH2Cl2/MeOH/26% NH4OH 90/10/1). The less polar fractions were evaporated to dryness to give the title compound I-dw in 65% yield. 1H-NMR (300 MHz, DMSO-d6, ppm from TMS): δ 10.72 (1H, bs), 6.16 (1H, bs), 4.69 (1H, m), 3.36-3.10 (7H, m), 2.60-1.10 (16H, m), 0.96 (3H, s), 0.83 (3H, s).
