실험 절차

To a solution of 3-{4-[5-(4-isobutyl-3-methyl-thiophen-2-yl)-[1,3,4]oxadiazol-2-yl]-2,6-dimethyl-phenoxy}-propane-1,2-diol (90 mg, 0.22 mmol) in THF (4 mL) are added NEt3 (0.14 mL) and, subsequently, methanesulfonlychloride (0.02 mL, 0.26 mmol). The mixture is stirred at rt for 3 h. A solution of NH3 in MeOH (7M, 4 mL) is added and the mixture is heated at 60° C. for 15 h. The mixture is evaporated, 1M aq. NaOH (3 mL) is added and the mixture is extracted with EA (2×20 mL). The organic extracts are dried (Na2SO4), filtered and evaporated to give crude 1-amino-3-{4-[5-(4-isobutyl-3-methyl-thiophen-2-yl)-[1,3,4]oxadiazol-2-yl]-2,6-dimethylphenoxy}-propan-2-ol; LC-MS: tR=0.86 min, [M+1]+=416.32.
