2-(4-Methoxyphenyl)propan-2-amine → N-[1-(4-Methoxyphenyl)-1-methylethyl]-3-oxo-4-androstene-17beta-carboxamide

Participants

Reaction Steps

610 mg of S-2-pyridyl 3-oxo-4-androstene-17β-thiocarboxylate [prepared as described in step (a) above] were dissolved in 1 ml of dry methylene chloride, and 630 mg of 1-(4-methoxyphenyl)-1-methylethylamine (prepared as described in Preparation 10a) were added to the resulting solution. The mixture was then stirred at room temperature for 3 days. At the end of this time, the reaction mixture was subjected, without further treatment, to silica gel column chromatography using a gradient elution method, with mixtures of methylene chloride and acetone in ratios ranging from 3:2 to 1:1 by volume as the eluent, and the product was recrystallized from diisopropyl ether, to give 670 mg of the title compound as white crystals.
