Intermediate 545A: 6-Chloro-N-((R)-2-fluoro-3-hydroxy-3-methylbutyl)-4-(((S)-tetrahydrofuran-3-yl)amino)nicotinamide [0628] (R)-4,6-dichloro-N-(2-fluoro-3-hydroxy-3-methylbutyl)nicotinamide (150 mg, 0.508 mmol), (S)-tetrahydrofuran-3-amine, HCl (62.8 mg, 0.508 mmol) and Hunig’s Base (0.266 mL, 1.525 mmol) were dissolved in DMF (5 mL) at room temperature with stirring and then heated at 120 C. overnight. The reaction mixture was cooled and the DMF removed under vacuum to afford the crude solid which was purified via column chromatography to afford 6-chloro-N-((R)-2-fluoro-3-hydroxy-3-methylbutyl)-4-(((S)-tetrahydrofuran-3-yl)amino)nicotinamide (112 mg, 61% yield) as a tan solid. LCMS 346.1 (M+H); 1H NMR (400 MHz, DMSO-d6) delta 8.77 (t, J=5.6 Hz, 1H), 8.67 (d, J=7.0 Hz, 1H), 8.40 (s, 1H), 6.75 (s, 1H), 4.81 (s, 1H), 4.37 (dd, J=9.4, 1.9 Hz, 0.5H), 4.28-4.16 (m, 1.5H), 3.88-3.77 (m, 2H), 3.76-3.67 (m, 2H), 3.62 (dd, J=14.5, 3.3 Hz, 1H), 3.55 (dd, J=9.2, 2.9 Hz, 1H), 3.42-3.32 (m, 1H), 2.30-2.20 (m, 1H), 1.79-1.69 (m, 1H), 1.14 (dd, J=5.9, 1.1 Hz, 6H).
204512-95-8, As the paragraph descriping shows that 204512-95-8 is playing an increasingly important role.
