PROCEDURE

实验过程

Esterify 13β-propyl-17β-hydroxy-gon-4-en-3-one (2.5 g.) with benzoyl chloride (2.0 g.). Purify the product by chromatography on Florex and recrystallize from ethyl acetate to obtain the title compound, m.p. 198°-200°; ultraviolet absorption peak at 240 mμ (ε25,000); infrared absorption peaks at 5.84, 6.00 μ.
