Versuchsvorschrift

HF-Pyridine (426 μL, 3.31 mmol) was added to a solution of 6-(((tert-butyldimethylsilyl)oxy)methyl)-N-(5-cyano-4-((2-methoxyethyl)amino)pyridin-2-yl)-7-(dimethoxymethyl)-3,4-dihydro-1,8-naphthyridine-1(2H)-carboxamide (intermediate 74, 900 mg, 1.577 mmol) in THF (7 ml) at room temperature. The reaction mixture was stirred for approximately 2 h, quenched with saturated aqueous NaHCO3 and partitioned with ethyl acetate. The aqueous layer was extracted with ethyl acetate and the combined organic layers were washed with brine, dried using Na2SO4, filtered and concentrated to give the title compound as a white solid. (UPLC-MS 3) tR 0.85 min; ESI-MS 457.1 [M+H]+. 1H NMR (400 MHz, CDCl3) δ 13.71 (s, 1H), 8.21 (s, 1H), 7.57 (s, 1H), 7.54 (s, 1H), 5.49 (s, 1H), 5.28 (s, 1H), 4.71 (d, 2H), 4.07-3.99 (m, 2H), 3.67-3.59 (m, 2H), 3.55 (s, 6H), 3.51-3.45 (m, 2H), 3.41 (s, 3H), 2.85 (t, 2H), 2.05-1.96 (m, 2H).
