Iodine → 3-(N-(N',N'-dimethylaminoethane)carbamoyl)cholesterol

Participants

Reaction Steps

Compound XIV was synthesized by mixing absolution of cholesteryl chloroformate (0.5 mmol) in chloroform with a solution of N,N-dimethylethylenediamine (9.1 mmol) in chloroform in a dry ice-ethanol bath. The solvent and the unreacted amine were removed in vacuo. Compound XIV was purified by two successive recrystallizations in ethanol. (Yield, 65%) TLC (chloroform:methanol=65:35) showed a single spot (Rf=0.37) when developed with iodine. The product was characterized by proton NMR.
