Reaction Conditions:
with triethylamine in dichloromethane at 20;
Steps:
chloroacetic acid cholesterylester (1): Slowly add a solution of 9.54 ml (120 mmol) chloroacetylchloride in 50 ml dichloromethane in drops to a solution of 38.67 g (100 mmol) cholesterol and 20.79 ml (150 mmol) triethylamine in 150 ml dichloromethane under refrigeration.Stir the formulation overnight at room temperature and then extract twice with 100 ml 2 N HCl each time.Remove the solvent and stir the residue in 200 ml dichloromethane with 5 g activated charcoal at room temperature.Filter off the activated charcoal, remove the solvent, and purify the residue via column chromatography on 50 g silica gel (dichloromethane).The yield is 45.04 g 1 as a colorless solid.
