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 (702 mg, 2.53 mmol), trans-3-(1H-pyrazol-1-yl)cyclopentylamine (460 mg, 3.04 mmol) and di-isopropylethylamine (0.970 mL, 5.57 mmol) in anhydrous DMSO (14 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 (Hexane/EtOAc=1/10→EtOAc) to yield (3S)-8-amino-9-fluoro-2,3-dihydro-3-methyl-7-oxo-10-[trans-3-(1H-pyrazol-1-yl)cyclopentylamino]-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carbonitrile (108 mg, 10%) as a yellow powder.
