실험 절차
Following a procedure similar to that of Example 1 but using 2.88 g of 5-carbamoyl-1-(4-nitrobenzyl)imidazolium-4-olate and 7.77 g of 2,3,4-tri-O-acetyl-α-L-rhamnopyranosyl bromide there was obtained 3.32 g of 1-(4-nitrobenzyl)-4-(2,3,4-tri-O-acetyl-α-L-rhamnopyranosyl)oxy-1H-imidazole-5-carboxamide.
