실험 절차

To a solution of crude 1-amino-3-{4-[5-(4-isobutyl-3-methyl-thiophen-2-yl)-[1,3,4]oxadiazol-2-yl]-2,6-dimethyl phenoxy}-propan-2-ol (0.22 mmol) in DMF (1 mL) are added glycolic acid (25 mg), DIPEA (0.1 mL) and finally TBTU (60 mg). The mixture is stirred for 15 h at rt, evaporated and the residue purified by TLC (SiO2, EA) to give 2-hydroxy-N-(2-hydroxy-3-{4-[5-(4-isobutyl-3-methyl-thiophen-2-yl)-[1,3,4]oxadiazol-2-yl]-2,6-dimethyl-phenoxy}-propyl)-acetamide (1.8 mg); LC-MS: tR=0.97 min, [M+1]+=474.26.
