Participants

Reaction Steps

To a solution of 2-tert-Butoxycarbonylamino-3-hydroxy-propionic acid methyl ester (0.400 g, 1.82 mmol) in dimethylformamide (15 ml) was added sodium hydride (65%)(0.145 g, 3.64 mmol) at 0° C. after the evolution of hydrogen gas ceased, the freshly distilled benzyl bromide (0.449 g, 1.82 mmol) was added to the solution. The reaction mixture was stirred at 25–30° C. for 5 hr to give a clear solution The solvent was then removed under reduced pressure below 40° C. The residue was dissolved in water (30 ml) and the solution extracted with ethyl acetate (two 20 ml portions). The combined organic layers were further washed with brine and dried over anhydrous sodium sulfate. The ethyl acetate was then removed under reduced pressure to give the 3-(biphenyl-4-ylmethoxy)-(2S)-tert-butoxycarbonylamino-propionic acid methyl ester as colorless oil (0.421 g, 60%). LC/MS (m/z): 386(M+1).
