実験手順

To 6.20 ml of an ice-cooled 20% solution of phosgene in toluene was slowly added a solution of 3 g 4-hydroxy-undecanoic acid hex-3-enyl ester and 0.93 g pyridine in 3 ml toluene. The reaction mixture was stirred for 16 hours at room temperature. A mixture of 3.48 g didecylamine and 0.93 g pyridine was added and the mixture was stirred for another 16 hours. Water was added and the mixture extracted with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate, 2N hydrochloric acid, water, dried over magnesium sulfate and evaporated to dryness. The residue was chromatographed on silica gel to give 2.9 g of a colorless liquid.
