Procedure

6-(Chloromethyl)nicotinic acid (172 mg, 1.00 mmol) obtained in Step 1, 2-amino-4-(2-furyl)-5-morpholinothiazole (251 mg, 1.00 mmol) obtained in Step 1 of Example 29 and PyBOP (572 mg, 1.10 mmol) were dissolved in DMF (4 mL), and triethylamine (0.307 mL, 2.20 mmol) was added thereto, followed by stirring at room temperature for 2 hours. The reaction mixture was poured into water, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under the reduced pressure. The resulting residue was purified through silica gel column chromatography (hexane:ethyl acetate=2:1 to 1:3) to afford the entitled Compound 36 (194 mg, 48%).
