실험 절차

N-(4-chloro-5-cyanopyridin-2-yl)-7-(dimethoxymethyl)-3,4-dihydro-1,8-naphthyridine-1(2H)-carboxamide (intermediate 2J, 40 mg, 0.103 mmol) and 2-methyl-2,8-diazaspiro[4.5]decane (31.8 mg, 0.206 mmol) were dissolved in DMF (1 ml) under argon. The mixture was stirred at 100° C. for 2 h. KF (12.0 mg, 0.206 mmol) and K2CO3 (42.8 mg, 0.309 mmol) were added to the reaction mixture and it was stirred at 100° C. for 3 h. Subsequently, the reaction mixture was cooled to room temperature, treated with conc. HCl (200 μl) and stirred for 30 min. The reaction mixture was diluted in EtOAc and washed with sat. aq. NaHCO3 (2×) and brine. The organic layer was dried over Na2SO4, filtered and concentrated under vacuum. The crude material was purified by normal phase chromatography (4 g silica gel cartridge, heptanes/EtOAc 100:0 to 0:100) followed by supercritical fluid chromatography (SFC 1, diethylaminopropyl stationary phase, DEAP column) to give the title compound as a white solid.
