실험 절차

In a mixed solvent (16 ml) of ethanol-water (9:1) were suspended 6-methoxy-4-{2-[(2R)-oxiran-2-yl]ethyl}pyrido[2,3-b]pyrazin-3(4H)-one (400 mg, 1.62 mmol) and 6-[(4R)-4-amino-2-oxopyrrolidin-1-yl]-2H-pyrido[3,2-b][1,4]oxazin-3(4H)-one (synthesized using [(3R)-5-oxopyrrolidin-3-yl]carbamic acid tert-butyl ester synthesized with reference to WO2004/22536 in the same manner as in Reference Examples 20, 21 and 22; 402 mg, 1.62 mmol) and stirred in a sealed tube at 80° C. for 16 hours. The solvent was removed from the reaction solution under reduced pressure and the obtained residue was purified by silica gel column chromatography (chloroform/methanol) to yield 323 mg (40%) of the title compound in the form of a yellowish solid.
