Reaction Steps
N,N-Diisopropylethylamine (2.0 mL, 0.011 mol) was added to a mixture of methyl 2-aminopropanoate hydrochloride (0.64 g, 0.0046 mol), 4-bromo-2-fluorobenzoic acid (1.0 g, 0.0046 mol) and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (2.12 g, 0.00479 mol) in N,N-dimethylformamide (10.0 mL, 0.129 mol). The reaction mixture was stirred overnight at RT, quenched with saturated sodium bicarbonate (25 mL) and extracted with EtOAc (3×40 mL). The combined organic layers were washed with brine, dried over anhydrous Na2SO4, filtered, and concentrated. The residue was purified by chromatography on silica gel with 60% EtOAc in hexanes to afford the desired product (1.33 g, 96%). LCMS: (M+H)=303.9/305.9.
