실험 절차

A solution of diazomethane (approximately 2.5 g., 0.06 mole) in ether (100 ml.) is mixed with a solution of 4-{3-[3-[2-(1-hydroxycyclohexyl)ethyl]-4-oxo-2-thiazolidinyl]propyl}benzoic acid (11.7 g., 0.03 mole) in ether (100 ml.). The resulting solution is allowed to stand at room temperature for 6 hours. Acetic acid is then added to destroy the excess diazomethane, and the solution is washed with dilute sodium bicarbonate solution and dried over sodium sulfate. Evaporation of volatile materials in vacuo yields the title compound as a nearly colorless, viscous oil.
