Reaction Steps
3β-tert-Butyldimethylsilyloxy-4,4-dimethyl-5α-chola-8,14-dien-24-ol (100 mg) is methylated with sodium hydride 60% (16 mg) and methyl iodine (0.125 ml) in 1 ml of DMF. The protecting tert-butyldimethylsilyl group is split of by treatment with HCl/ethanol. After aqueous work-up and crystallisation from methanol/water, the title compound (5 mg) is isolated.
