Reaction Steps

Reductive Amination Method B: 6-Bromopyridine-2-carbaldehyde (1.3 g, 7.0 mmol) was added to a 200 ml, round bottom under argon. Dichloroethane (28.0 ml) was added followed by (3S)-3-methylmorpholine (HCl salt) (1 g, 7.3 mmol) and triethylamine (1.0 ml, 7.3 mmol). The mixture was stirred for 0.5 hours at room temperature followed by the addition of sodium triacetoxyborohydride (2.07 g, 9.8 mmol) and the resulting slurry was maintained at room temperature overnight. The reaction was quenched by the careful addition of saturated aqueous sodium bicarbonate and was extracted once with DCM and once with ethyl acetate. The combined organics were dried over magnesium sulfate, filtered, and concentrated in vacuo. The resulting oily residue was purified via flash chromatography (silica, 0-10% methanol/ethyl acetate) to afford the title compound as a colorless oil.
