Reaction Steps

2-Amino-4-(2-furyl)-5-(2-methoxypyridin-5-yl)thiazole (1.32 g, 4.83 mmol) obtained in Step 2 was suspended in a mixture of 48% hydrobromic acid (4 mL) and acetic acid (4 mL), followed by stirring at 100° C. for 2 hours. The reaction mixture was neutralized with a 10 mol/L aqueous solution of sodium hydroxide added thereto, and the precipitated solid was collected by filtration. The resulting solid was purified through silica gel column chromatography (chloroform:methanol=4:1) to afford the entitled Compound q (870 mg, 70%).
