Versuchsvorschrift

To 20 ml of acetone were added 1.07 g of N-methylaniline and 1.38 g of anhydrous potassium carbonate, and a solution obtained by dissolving 2.63 g of O-3-tert-butyl-4-chlorophenyl chlorothioformate into 20 ml of acetone was added thereto with stirring at room temperature. After stirring for 30 minutes as it is, the mixture was subjected to refluxing with heating for 2 hours. The reaction mixture was cooled down to room temperature and then poured into cold water. The product was extracted with benzene. The benzene solution was washed with water and a saturated aqueous solution of sodium chloride in this order, and dried over anhydrous magnesium sulfate. Thereafter, benzene was distilled off. The residue was purified through a column chromatography (employing silica gel as carrier, and benzene/hexane=1/1 (V/V) as developing solvent) and further recrystallized form ethanol to give 2.64 g of O-3-tert-butyl-4-chlorophenyl N-methyl-N-phenylthiocarbamate, having melting point of 65°-67° C.
