Reaction Steps
2-Amino-3-bromo-5-fluoropyridine (1.127 g, 5.90 mmol) and BrettPhos Precatalyst (0.141 g, 0.177 mmol) were mixed under an argon atmosphere. Methylamine (2.0 M in THF, 4.43 ml, 8.85 mmol) and lithium bis(trimethylsilyl)amide (1.0 M in THF, 14.75 ml, 14.75 mmol) were added slowly via syringe, and the reaction mixture was stirred at room temperature for 3.5 h. The reaction mixture was quenched with saturated aqueous ammonium chloride and extracted three times with a 9:1 mixture of DCM to MeOH. The combined organic layers were dried over magnesium sulfate, filtered, and concentrated in vacuo. The resulting crude product was purified by silica gel column chromatography eluting with acetone in DCM to yield the title compound (0.497 g, 3.52 mmol, 59.7% yield) as a tan solid. M+1: 142.1.
