실험 절차

1-Benzyloxycarbonylpiperidine-4-carboxylic acid (5.00 g, 19.0 mmol) was dissolved in dichloromethane (80 mL), and thionyl chloride (6.93 mL, 95.0 mmol) and DMF (0.15 mL, 1.90 mmol) were added thereto, followed by 178, stirring under heating and reflux for 3 hours. The reaction mixture was concentrated under reduced pressure, and the resulting residue was dissolved in dichloromethane (2 mL). The resulting solution was added to a solution of 2-amino-4-(2-furyl)-5-morpholinothiazole (2.01 g, 8.00 mmol) in pyridine (32 mL) obtained in Step 1 of Example 29, and then N,N-dimethylaminopyridine (97.6 mg, 0.800 mmol) was added thereto, followed by stirring at room temperature for 1 hour. The solvent was distilled away under reduced pressure, and the resulting residue was purified through silica gel column chromatography (hexane:ethyl acetate=1:1 to 1:3) to afford the entitled Compound 43 (4.96 g, 100%).
