実験手順

A mixture of 0.47 g of N1-tert-butyl-4-trifluoromethylbenzene-1,2-diamine, 0.51 g of isonicotinealdehyde-bisulfite adduct and 5 ml of N,N-dimethylformamide was stirred for 10 minutes at 150° C. The reaction mixture was ice-cooled, then, a 10% sodium hydroxide aqueous solution was poured, and the mixture was extracted with methyl tert-butyl ether. 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 0.26 g of 1-tert-butyl-2-(pyridin-4-yl)-5-trifluoromethyl-1H-benzimidazole (hereinafter, referred to as present active compound 220).
