Procedure

Compound 419 (192 mg, 0.824 mmol) and triethylamine (0.379 mL, 2.72 mmol) were dissolved in THF (4 mL), and bromoacetyl bromide (0.215 mL, 2.47 mmol) was added thereto at 0° C., followed by stirring at room temperature for 1 hour. At 0° C., a solution (2 mL) of morpholine (1.08 mL, 12.4 mmol) in THF and triethylamine (1.73 mL, 12.4 mmol) was added to the reaction mixture, followed by stirring at room temperature for 1 hour. Water was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography to afford the entitled Compound 421 (229 mg, 77%).
