Versuchsvorschrift

In a 3000 ml flask equipped with a stirrer and a condenser were charged 132 g of 11-bromoundecanoic acid, 91.5 g of n-decanthiol, 59.4 g of sodium methoxide (28% methanol solution) and 1500 ml of methanol, and the mixture was refluxed for 12 hours. After completion of the reaction, the reaction mixture was cooled to room temperature, precipitated crystals were collected by filtration under reduced pressure and the resulting crystals were washed with methanol. The resulting crystals were suspended in 5000 ml of distilled water, and the suspension was neutralized by a conc. hydrochloric acid, and the crystals were again collected by filtration under reduced pressure. The crystals were washed with water until the washed solution became neutral, and recrystallized from ethanol to obtain 140.5 g of the title compound.
