실험 절차

A mixture of (3S)-8-amino-9,10-difluoro-2,3-dihydro-3-methyl-7-oxo-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carbonitrile (1.30 g, 4.69 mmol), (1S,3S)-3-(2-pyridyl)cyclopentylamine (913 mg, 5.63 mmol) and triethylamine (1.30 mL, 9.33 mmol) in anhydrous DMSO (8 mL) was stirred at 100° C. for 7 h. After cooling, the reaction mixture was poured into ice-water and then extracted with CH2Cl2-MeOH. The organic layer was washed with water and brine, and dried over anhyd Na2SO4 followed by the removal of solvent. The crude product was purified by column chromatography (EtOAc) to yield (3S)-8-amino-9-fluoro-2,3-dihydro-3-methyl-7-oxo-10-[(1S,3S)-3-(2-pyridyl)cyclopentylamino]-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carbonitrile (364 mg, 19%) as a yellow powder.
