PROCEDURE

实验过程

A solution of 3α-hydroxy-11-oxo-5α-androstane-17β-carboxylic acid (521 mg.) in dry acetone (50 ml.) was refluxed with triethylamine (1.04 ml.) and n-butyl iodide (0.87 ml.) for 16 hours. The mixture was evaporated to a residue which was dissolved in chloroform, washed with water, dried (Na2SO4) and evaporated to a foam (534 mg.). A solution of the foam in ether was washed with saturated sodium bicarbonate solution and with water, dried (Na2SO4) and evaporated to give title compound (443 mg.) as a white foam, [α]D + 51°.
