40 °C

16 parts of 80 percent strength by weight 3-isopropyl-5-methyl-phenol in 30 parts of methylene chloride are added to 12.7 parts of N,N-bis-fluoromethyl-carbamic acid fluoride (from Example 2) in 50 parts of methylene chloride. 10.1 parts of triethylamine in 20 parts of methylene chloride are then added. The reaction mixture is stirred for one hour at 40° C. and when it has cooled it is extracted by shaking with 10 percent strength by weight sodium hydroxide solution and water, dried and distilled to dryness under reduced pressure. 24.1 parts (95% of theory) of O-3-isopropyl-5-methyl-phenyl N,N-bis-fluoromethyl-carbamate of boiling point 120° C./0.05 mm Hg are obtained.
