A mixture of 5,N2-dimethylpyridin-2,3-diamine (1.13 g), 2-ethylsulfanylbenzoic acid (1.79 g), WSC (1.38 g), and pyridine (20 ml) was stirred with heating under reflux at 120° C. for 2 hours. Into the reaction mixture cooled to room temperature, water was poured, and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to give 1.58 g of 2-ethylsulfanylphenyl-N-(5-methyl-2-methylaminopyridin-3-yl)-benzamide (Compound (1B)-514).
