A mixture of 430 mg Boc-L-propargylglycine, 269 mg benzyl azide, 36 mg copper(II)acetate and 80 mg sodium ascorbate in 15 ml water/t-BuOH (1:1) was stirred for 12 h at RT. The reaction mixture was diluted with ethyl acetate, washed with brine (2×) and the aqueous phase reextracted with ethyl acetate. The crude product obtained after evaporation of the solvent was pure enough for the subsequent transformation. Yield: 855 mg.
