Reaction Steps

To a solution of 5.62 g Z-Gly-OH in 100 ml DMF were added 13.7 ml N-ethylmorpholine, 8.8 g TOTU and 5.0 g 1-butoxycarbonylpiperazine. After stirring for 12 h, aqueous NaHCO3 was added and the reaction mixture was diluted with ethyl acetate and washed with aqueous LiCl (4%) and 0.1 M HCl. The crude product obtained after evaporation of the solvent was purified by flash chromatography on silica using an ethyl acetate/heptane gradient. Yield: 6.34 g
