Reaction Steps

2-methylpyridin-4-ylboronic acid (327 mg, 2.39 mmol), (S)-tert-butyl 1-(3-bromo-5-chlorophenylamino)-1-oxo-3-phenylpropan-2-ylcarbamate (542 mg, 1.19 mmol), tetrakis(triphenylphosphine)palladium (345 mg, 0.30 mmol), cesium fluoride (544 mg, 3.58 mmol) were added to a vial then DME (4778 μl, 1194 μmol) was added and the mixture was heated to 85° C. for 8 h. The reaction was loaded and purified on Phenomenex Geminni C18 HPLC 50 mm×250 mm running ACN/Water/0.1% TFA in a linear gradient. The fractions containing the desired product were combined and concentrated to afford tert-butyl (S)-1-(3-chloro-5-(2-methylpyridin-4-yl)phenylamino)-1-oxo-3-phenylpropan-2-ylcarbamate (367 mg, 66% yield). tert-butyl (S)-1-(3-chloro-5-(2-methylpyridin-4-yl)phenylamino)-1-oxo-3-phenylpropan-2-ylcarbamate (367 mg, 0.78 mmol) was dissolved in DCM (3 mL) and TFA (1 mL) add stirred for 3 h. The solution was concentrated to afford (2S)-2-amino-N-(3-chloro-5-(2-methylpyridin-4-yl)phenyl)-3-phenylpropanamide (280 mg, 99%).
