실험 절차

A mixture of 3-(1,2,4-thiadiazol-5-yl)-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyrazine (I115) (50 mg, 0.240 mmol) and triethylamine (0.050 mL, 0.360 mmol) in DCM (1.5 ml) was treated with 3-chloro-4-fluoro-2-methylbenzoyl chloride (I58) (54.7 mg, 0.264 mmol) in DCM (0.5 ml) and stirred at room temp for 1 h. After 1 h, 2 drops of methanol and then NaHCO3 solution (5 ml) and ethyl acetate (30 ml) were added. The product was extracted into the ethyl acetate which was dried (Na2SO4) and concentrated. Purification by high pH MDAP gave desired product as a white solid in 44 mg.
