Triethylamine → HCID 18625877, compound

Participants

Reaction Steps

Triethylamine (0.29 ml) and methanesulfonyl chloride (0.12 ml) were added to a solution of ethyl 3-[4-(2-hydroxyethoxy)phenyl]-2-(2-phenoxyethyl)propionate (503 mg), which is the product of Reference example 3(f), in anhydrous dichloromethane (10 ml). The reaction mixture was stirred at ambient temperature for 2 hours. At the end of this time the reaction mixture was concentrated. The residue was partitioned between ethyl acetate and water. The ethyl acetate layer was separated and dried over anhydrous magnesium sulfate and then concentrated. The residue was purified via chromatography on silica gel column using hexane/ethyl acetate=2/1-3/2 as the eluant to afford the desired compound (632 mg) as a syrup.
