Dimethylformamide → N-(3-{5-[1-(2-Phenoxy-acetyl)-piperidin-2-yl]-[1,2,4]oxadiazol-3-yl}-phenyl)-succinamic acid

Participants

Reaction Steps

0.1 mmol of 1-{2-[5-(3-Amino-phenyl)-2H-[1,2,4]triazol-3-yl]-piperidin-1-yl}-2-phenoxy-ethanone were dissolved in 1 ml DMF and 1 eq of succinic anhydride added. The reaction was stirred overnight and the intermediate (N-(3-{5-[1-(2-Phenoxy-acetyl)-piperidin-2-yl]-[1,2,4]oxadiazol-3-yl}-phenyl)-succinamic acid) isolated via preparative HPLC. The isolated material was redissolved in DMF and 1 eq of HATU was added. The reaction mixture was heated to 120° C. using microwave heating. The product was isolated via preparative HPLC.
