Reaction Steps
To a mixture of 1-aminopropan-2-ol (2 g, 26.6 mmol) and TEA (4.03 g, 39.9 mmol) in DCM (50 mL) was added ethyl 2-chloro-2-oxoacetate (4.36 g, 31.95 mmol) dropwise at 0° C. The mixture was stirred at room temperature for 16 h. The mixture was diluted with DCM and extracted with brine. The organic layer was dried and concentrated to give a crude product which was purified by silica gel chromatography eluting with petroleum ether/ethyl acetate (2:1) to give ethyl 2-(2-hydroxypropylamino)-2-oxoacetate (2.19 g, 51% yield) as yellow syrup. LCMS retention time 0.348 min, LCMS MH+ 176.
