Dicyclohexylcarbodiimide → HCID 18650840, compound

Participants

Reaction Steps

0.47 g of (S,S)-4-[4'-(3"-chloro-1"-methylbutoxy)-phenyl]benzoic acid, 0.20 g of 4-n-propylphenol, 0.32 g of dicyclohexylcarbodiimide, 0.04 g of 4-pyrrolidino-pyridine and 6 ml of methylene chloride were stirred together at room temperature for five hours. The dicyclohexyl urea thus precipitated was filtered and the filtrate was desolvated. The crude product thus obtained was purified by silica gel column chromatography with the use of a mixture of n-hexane and ethyl acetate (17:3) as a developing solvent. Thus 0.4 g of the title compound was obtained.
