実験手順: To a solution of formyl succinonitrile potassium salt (6.67 g, 45.6 mmol) and 1,1-bis(4-fluorophenyl) methaneamine (11.0 g, 50.2 mmol) in water (19 ml) was added acetic acid (19 ml) at room temperature, and the mixture was stirred 100° C. for 30 minutes. The solvent was distilled off under reduced pressure. The residue was poured into iced water, made basic with potassium carbonate and then extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure to give the objective product as oily matter. Yield (amount) 14.0 g, yield (rate) 99.3% The solvent was distilled off under reduced pressure The residue was poured into iced water extracted with ethyl acetate The extract was washed with water dried over anhydrous magnesium sulfate the solvent was distilled off under reduced pressure to give the objective product as oily matter Yield (amount) 14.0 g yield (rate) 99.3%

実験手順: A mixed solution of bis(4-fluorophenyl)methylformamide (13.9 g, 56.2 mmol), concentrated hydrochloric acid (80 ml) and methanol (160 ml) was stirred at 90° C. for 1.5 hours and cooled to room temperature, then a 6 N aqueous sodium hydroxide solution (170 ml) was added thereto, and the mixture was extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure to give the objective product as a solid material. Yield (amount) 11.5 g, yield (rate) 93.5% the mixture was extracted with ethyl acetate The extract was washed with water dried over anhydrous magnesium sulfate the solvent was distilled off under reduced pressure

実験手順: To a stirred solution of 2-(6-bromobenzo[d]isoxazol-3-yl)benzaldehyde (compound 7) (2 g) in dichloromethane (33 mL) was added bis(4-fluorophenyl)methanamine (1.74 g) and anhydrous magnesium sulfate and stirred under nitrogen at room temperature for 18 h. Filtration and evaporation of the filtrate and crystallisation from dichloromethane-methanol gave the title compound (2.4 g).
