Procedure

2-tert-butoxycarbonylamino-6-[2-(5-ethyl-4-methyl-1,3-thiazol-2-yl)ethyl]-4-morpholinopyridine (500 mg) obtained in Example 109-(1) was dissolved in dimethylformamide (12 ml), and 60% sodium hydride (58 mg) was added under cooling with ice, followed by stirring at room temperature for one hour. The reaction solution was cooled with ice, and a solution of methyl 3-chloro-5-chloromethylbenzoate (438 mg) in dimethylformamide (5 ml), was added thereto, followed by stirring at room temperature for 13 hours. The reaction solution was diluted with ethyl acetate, washed with water and a saturated sodium chloride aqueous solution and then, dried over anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=1/2) to obtain the above identified compound (628 mg).
