Procedure

Then, a solution of 30.0 g (0.064 mole) of 1,1-bis(4-(4-nitrobenzoyl)phenyl)methane in 1 liter of tetrahydrofuran was added dropwise for 1 hour, and stirred for 8 hours with maintaining at 3° to 5° C. At that time, hue was changed to dark purple. After the end of the reaction was confirmed by a liquid chromatography, the solution was poured in 400 milliliters of ice water, and extracted with 800 milliliters of chloroform after adding 400 milliliters of a 4N-HCl aqueous solution. Thereafter, the solution was washed with a 6N-HCl aqueous solution, an aqueous solution of sodium hydrogencarbonate, brine and water, and then removed off chloroform by a rotary evaporator. The residue was dissolved in toluene and treated with a silica gel (800 g) column, to obtain 17.1 g of 1,1-bis(4-(1-(4-nitrophenyl)butylidene)phenyl)methane as highly viscous oil.
