Triethylamine → N-((5-(4-((3-fluorobenzyl)oxy)phenyl)-1,3,4-thiadiazol-2-yl)methyl)-2-hydroxy-8-(4-methylthiazol-5-yl)octanamide

Participants

Reaction Steps

A mixture of 2-hydroxy-8-(4-methylthiazol-5-yl)octanoic acid (40.0 mg, 0.155 mmol), 1-hydroxybenzotriazole hydrate (21.0 mg, 0.155 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (44.7 mg, 0.233 mmol), triethylamine (0.06 mL, 0.466 mmol) and (5-(4-((3-fluorobenzyl)oxy)phenyl)-1,3,4-thiadiazol-2-yl)methanamine (54.7 mg, 0.155 mmol) in dimethylformamide (0.78 mL) was stirred at room temperature for 22 h. The resulting mixture was concentrated and the residue was purified via silica gel chromatography (Analogix IF-280, SF25-40 g column, gradient 90:10-80:20 heptane:EtOAc) to yield N-((5-(4-((3-fluorobenzyl)oxy)phenyl)-1,3,4-thiadiazol-2-yl)methyl)-2-hydroxy-8-(4-methylthiazol-5-yl)octanamide. MS (ES+) 555 (M+1).
