PROCEDURE

实验过程

3β-tert-Butyldimethylsilyloxy-4,4-dimethyl-5α-chola-8,14-dien-24 oic acid (0.50 g) is dissolved in 15 ml of dry dichloromethane. After cooling to −15° C., 0.188 ml of N-methylmorpholine and 0.153 ml of isobutylchloroformiate is added and the mixture is stirred at −15° C. for 20 minutes, whereupon 0.44 ml of aniline is added. The mixture is stirred overnight and the temperature is slowly elevated to room temperature. After aqueous work-up and crystallization from methanol, 3β-tert-butyldimethylsilyloxy-4,4-dimethyl-5α-chola-8,14-dien-24-oic acid-N-phenyl amide (0.431 g) is obtained. H-NMR (CDCl3, 400 MHz): δ=7.53 (2H, d); 7.34 (2H, t); 7.17 (1H, s); 7.12 (1H, t); 5.35 (1H, s); 3.21 (1H, m); 0.9 (9H, s); 0.04 (6H, m).
