실험 절차

To a solution of 5-[[[(1,1-dimethylethoxy)carbonyl]amino]methyl]-1,3,4-oxadiazole-2-carboxylic acid ethyl ester (prepared as described in JOC (1995), 60(10), 3112-20) (0.150 g) in methanol (5 ml) was added a solution of 2.0M ethylamine in tetrahydrofuran (3 ml). The solution was left standing at 20° C. for 1.5 h. The solvent was removed by evaporation using a stream of nitrogen to give the title compound as a yellow gum (0.139 g).
