Yield

With pyridine In tetrahydrofuran for 12h; Cooling with ice;

Experimental Procedure
In an ice-water bath, dissolve 32.817g (100mmol) of 4,4′-diaminooctafluorobiphenyl in 300mL of tetrahydrofuran, then add 16.5mL (200mmol) of pyridine solution, after dissolving, slowly add 50.712g dropwise (200mmol) of 4-nitro-2-trifluoromethyl benzoyl chloride, after the dripping is completed, the reaction is fully stirred for 12h to produce a precipitate; the precipitate is filtered, thoroughly washed with tetrahydrofuran and deionized water, and then The precipitate was dried under reduced pressure at 100°C for 12 hours, and pulverized to obtain a solid powder (yield 87.1%), which is the nitro compound of the diamine precursor represented by formula (3);
