On saponification of the acetate with sodium ethylate, hippocoprosterol 
was obtained, melting at 79° C. 
Hippocoprosterol Benzoate—The hippocoprosterol was mixed with an equal 
weight of benzoic anhydride, and heated to 160° for two hours in an open 
vessel. The product was boiled with alcohol, and on cooling the benzoate 
separated in thick clots. These were recrystallised several times from 
petrol, and finally from ethyl acetate. Hippocoprosterol benzoate crystallises: 
in microscopic needles, which in mass appear as sticky lumps. It is 
difficultly soluble in alcohol and ethyl acetate (but more so than the mother 
substance), easily in ether, petrol, and benzene. The meiting point is 
58°5 to 59°5 C. In concentrated ether solution it proved optically inactive, 
and on analysis gave the following figures :—

Two grammes of the benzoate were saponified with sodium ethylate and 
yielded hippoeoprosterol, melting at 79°. 
Hippocoprosterol Cinnamate.*—Five parts of hippocoprosterol were mixed 
with three parts of cinnamyl chloride and heated to 140° for one hour. 
The product was boiled out with alcohol, and the solution on cooling 
deposited the cinnamate in masses of minute needle-shaped crystals which, 
when dry, appeared sticky, caking together under pressure. It is very 
soluble in benzene, moderately in acetic ether and petrol, and difficultly 
in alcohol. The melting point is 62°C. On analysis the following figures 
were obtained :— 
0°2040 gave 0°6143 CO, and 0:2132 H,0.
