Dicyclohexylcarbodiimide → HCID 18650834, compound

Participants

Reaction Steps

1.00 g of 4-(3'-chloro-1'-methylbutoxy)benzoic acid, 0.50 g of 4-cyanophenol, 0.93 g of dicyclohexylcarbodiimide, 0.10 g of 4-pyrrolydinopyridine and 10 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 ethyl acetate and n-hexane (1:4) as a developing solvent to thereby give the title compound.
