Participants

Reaction Steps

A solution of the compound (0.20 g) obtained in Example 261 and N-methylethanamine (0.11 mL) in acetonitrile (2.7 mL) was stirred at room temperature for 3 hr. The reaction mixture was diluted with ethyl acetate, washed with water, saturated aqueous sodium hydrogen carbonate solution, saturated aqueous ammonium chloride solution and saturated brine, dried and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (solvent gradient; 80→100% ethyl acetate/hexane) to give the title compound (0.15 g, 83%) as a white powder.
