Participants

Reaction Steps

(4-(3-(2-naphthylmethylamino)propyl)-8-hydroxy-3,4-dihydro-2H-1,4-benzoxazine (166 mg) was dissolved in DMF (3 ml), and potassium carbonate (63 mg) and methyl bromoacetate (0.045 ml) were added. to the resultant solution at 0° C., followed by stirring at room temperature for 16 hours. The reaction solution was diluted with ethyl acetate, washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was then distilled off under reduced pressure, and the residue was purified by column chromatography (silica gel:ethyl acetate/n-hexane=2:3) to obtain the object compound (140 mg, yield 73%).
