الإجراء التجريبي

139 grams (1 mole) of 3-nitro-phenol and 28 grams (0.5 mole) of potassium hydroxide were dissolved in 400 milliliters of dimethyl formamide, and 140 grams (1.2 mole) of trifluoro-chloroethylene were introduced in a gas pipe at 40° C; the mixture was then maintained at 60° C for 2 hours. The main amount of dimethyl formamide was distilled off in vacuo. The residue was poured into ice water, separated, dried over Na2SO4 and distilled in vacuo.
