Reaction Steps

To a solution of the compound of Example 537 (215 mg, 0.417 mmol), 2-aminoethanol (32.5 μL, 0.542 mmol) and HOBt (84.6 mg, 0.626 mmol) in DMF (5 mL) was added WSCD (120 mg, 0.626 mmol) under ice-cooling, and the mixture was stirred at room temperature for 15 hr. The reaction mixture was diluted with saturated aqueous sodium hydrogen carbonate solution, and extracted twice with ethyl acetate. The extract was combined, washed with saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by aminosilica gel chromatography (eluate; ethyl acetate/methanol=10/0-8/2). Recrystallization of the obtained solid from ethyl acetate-THF gave the title compound (131 mg, 56%) as a white powder.
