Acetone → HCID 13656345, compound

Participants

Reaction Steps

To 20 ml of acetone were added 1.25 g of 4-fluoro-N-methylaniline and 1.38 g of anhydrous potassium carbonate, and a solution obtained by dissolving 2.5 g of 3-tert-butyl-4-chlorophenyl chloroformate into 20 ml of acetone was added thereto with stirring at room temperature. After stirring for 30 minutes as it is, the mixture was refluxed with heating for 2 hours. After cooled down to room temperature, the reaction mixture was poured into cold water and the resultant product was extracted with benzene. The benzene solution was washed with water and a saturated aqueous solution of sodium chloride in this order, dried over anhydrous magnesium sulfate, and thereafter benzene was distilled off under reduced pressure. The residue was purified through a column chromatography (employing silica gel as carrier and benzene as developing solvent) and further recrystallized from ethanol to give 2.7 g of 3-tert-butyl-4-chlorophenyl N-(4-fluorophenyl)-N-methylcarbamate having melting point of 92°-94° C.
