YieldReaction ConditionsOperation in experiment
With hydrogen In ethyl acetate at 20℃; for 1.5h; 209 A mixture of 5.46 g of N-isopropyl-2-nitro-4- trifluoromethylaniline, 30 ml of ethyl acetate and 5% palladium charcoal (catalytic amount) was stirred for 1.5 hours at room temperature under a hydrogen atmosphere of about 1 atm. The reaction mixture was filtrated through Celite (registered trademark) . The filtrate was washed with water, dried over sodium sulfate, then, concentrated under reduced pressure, to obtain 4.35 g of Nl-isopropyl-4-trifluoromethylbenzene- 1, 2-diamine.1H-NMR (CDCl3) δ: 7.08 (dd, IH), 6.93 (d, IH), 6.63 (d, IH), 3.65 (brs, IH), 3.54 (brs, IH), 3.31 (br s, 2H), 1.25 (d, 6H) .

YieldReaction ConditionsOperation in experiment
In N,N-dimethyl-formamide at 150℃; for 1h; 219 Production Example 219; A mixture of 0.44 g of Nl-isopropyl-4- trifluoromethylbenzene-1, 2-diamine, 0.51 g of isonicotinealdehyde-bisulfite adduct and 4 ml of N, N- dimethylformamide was stirred for 1 hour at 150°C. The reaction mixture was allowed to cool to room temperature, and water was poured into this, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, dried over sodium sulfate, then, concentrated under reduced pressure to obtain a solid residue. The residue was washed with hexane, to obtain 0.50 g of l-isopropyl-2- (pyridin-4-yl- ) -5- trifluoromethyl-lH-benziinidazole (hereinafter, referred to as present active compound 219) . Present active compound 219 1H-NMR (CDCl3) δ: 8.84 (dd, 2H), 8 .12 (d, IH), 7.74 (d, IH), 7.58-7.55 (m, 3H), 4.88-4.78 (m, IH) , 1.70 (d, 6H) .
