Procedure

2-Amino-4-(2-furyl)-5-(1-methyl-2-oxo-1,2-dihydropyridin-4-yl)thiazole (222 mg, 0.812 mmol) obtained in Step 1 was dissolved in DMF (4 mL), and isonicotinic acid (199 mg, 1.62 mmol), PyBOP (926 mg, 1.78 mmol) and triethylamine (0.497 mL, 3.56 mmol) were added thereto, followed by stirring at 80° C. for 1 hour. The reaction mixture was poured into water, and the precipitated solid was collected by filtration. The resulting solid was purified through silica gel column chromatography (chloroform:methanol=17:3), followed by reslurrying with methanol to afford the entitled Compound 123 (158 mg, 52%) as a pale yellow solid.
