Reaction Steps
3β-Hydroxy-4,4-dimethyl-5α-chola-8,14-dien-24-oic acid (100 mg) is suspended in 5 ml of dry DMF. 811 mg of cesium carbonate and 0.29 ml of benzyl chloride is added and the mixture is stirred at 50° C. overnight. After aqueous work-up, column chromatography and crystallisation from acetone/water 55 mg of the title compound is obtained. Melting point: 118-119° C.
