Procedure
To a solution of 4-[5-(N-t-butoxycarbonylamino)valeryl]morpholine (1.656 g) in dry N,N-dimethylformamide (20 ml) were added sodium hydride (60% dispersion in mineral oil : 347 mg) and methyl iodide (2.462 g) at 0°-5° C. under nitrogen atmosphere. After being stirred for 6 hours at room temperature, the reaction mixture was added to ethyl acetate (200 ml) and water (200 ml). The organic layer was washed with 0.5 N hydrochloric acid (200 ml), water (200 ml), aqueous sodium bicarbonate (200 ml), water (200 ml) and brine (200 ml) successively, and dried over magnesium sulfate. Evaporation of the solvent gave 4-[5-(N-methyl-N-t-butoxycarbonylamino)valeryl]morpholine (1.093 g) as an oil.
