Reaction Steps

N-(4-chloro-5-cyanopyridin-2-yl)-7-(dimethoxymethyl)-3,4-dihydro-1,8-naphthyridine-1(2H)-carboxamide (intermediate 2J, 106 mg, 0.273 mmol) and KF (159 mg, 2.73 mmol) were dissolved in DMSO (3 ml). The mixture was stirred at 110° C. for 16 h. The mixture was cooled to room temperature, diluted in EtOAc and washed with sat. aq. NaHCO3 (2×) and brine. The org. 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 60:40) to give the title compound as a white solid. (UPLC-MS 3) tR 1.20 min; ESI-MS 372.1 [M+H]+.
