Sodium bis(trimethylsilyl)amide → HCID 58266623, compound

Participants

Reaction Steps

Sodium bis(trimethylsilyl)amide (3.9 mL, 3.90 mmol) was added to a solution of 5′-bromo-6′-chloro-2-fluoro-5-(4-piperidin-1-ylmethyl-phenyl)-[3,4]bipyridinyl-3′-ylamine (187 mg, 0.39 mmol) in anhydrous THF (7.0 mL) and the resultant solution stirred at ambient temperature for 20 min. The reaction mixture was diluted with water (20 mL) and extracted with DCM: MeOH (4:1, 3×20 mL). The combined organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The resultant residue was purified by flash chromatography (silica, 4 g column, ISCO, 0-15% MeOH in DCM) to afford the title compound as a beige powder (30 mg, 17%). 1H NMR (CDCl3, 400 MHz): 9.17 (d, J=2.0 Hz, 1H), 8.86 (d, J=2.0 Hz, 1H), 8.67 (s, 1H), 7.65 (d, J=7.5 Hz, 2H), 7.49 (d, J=7.5 Hz, 2H), 3.59 (s, 2H), 2.51-2.47 (m, 4H), 1.68-1.59 (m, 4H), 1.51-1.45 (m, 2H). LCMS (Method A): RT=7.10 min, M+H+=455/457.
