The synthetic route is as follows., 7343-33-1
2- [6-Chloro-3- (ethanesulfonyl) pyridin-2-yl] -3-methyl-6- (trifluoromethyl)-3H-imidazo [4,5-b] 300mg, potassium carbonate 133 mg, and to a mixture of 3 mL of DMF, was added 3-bromo-1H-1,2,4-triazole 132mg under ice-cooling. After the mixture was stirred under ice-cooling for 2.5 hours, a saturated aqueous solution layer was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, and saturated brine, and dried with anhydrous sodium sulfate. The resulting organic layer was dried under reduced pressure. The resulting residue was subjected to silica gel chromatography to obtain 370mg of the compound of the present invention beta3 referred to below.
