Reaktionsschritte
The last remains of the product (3) from the mother liquor were obtained by column chromatography of the mother liquor (adsorbed on silica gel) on a small column of silica gel (80-200 mesh) utilizing hexane-acetone (85:15) as eluent. An additional 0.15 gm of 7-oxo-DHEA-Ac (3) was obtained. Total yield 1.75 gm, 56.5% (based on 90% conversion), melting point 185-186° C.
