Reaction Steps

To a screw-capped test tube, N-(2-thienylcarbonyl)glycine (56 mg, 0.3 mmol), 6-methoxy-2-pyridinecarboxaldehyde (46 mg, 0.3 mmol), sodium acetate (25 mg, 0.3 mmol) and acetic anhydride (0.3 mL) were added. The test tube was sealed, and it was then stirred at an external temperature of 90° C. Three hours later, the temperature of the reaction solution was returned to room temperature, and water (1.5 mL) was then added thereto. The obtained mixture was stirred at the same temperature as described above for 1.5 hours. Thereafter, the precipitated crystal was collected by filtration, and it was washed with water (5 mL) and was then dried under reduced pressure, so as to obtain 38 mg of the above-captioned compound.
