実験手順
An amount of 236 g. (1 mole) 3,5-dichloro-2-nitrobenzoic acid (Step 1) and 424 g. (2.1 moles) 1-dodecanethiol in 1.5 liter ethanol and 1 liter water was purged with nitrogen for 15-30 min. Then 430 g. (3.1 moles) anhydrous potassium carbonate were added and the reaction mixture was refluxed under an atmosphere of nitrogen for 60-72 hr. After cooling to room temperature, the solution was poured slowly into a rapidly stirred mixture of 6 liters water, 360 ml. conc. HCl and crushed ice. The precipitated solid was collected and washed well with water. The yellow material was slurried in 2.7 liters of glacial acetic acid, filtered, washed with a small amount of glacial acetic acid and dried in vacuo at 45° C. An amount of 560 g. of the product was obtained, m.p. 74°-77° C.
