Phenylpropiolic Acid → 3-phenyl-N-(1-(thiazol-2-yl)piperidin-4-yl)propiolamide

Participants

Reaction Steps

A solution of 500 mg (1.68 mmol) 1-(thiazol-2-yl)piperidin-4-amine trifluoroacetate, 332 mg (2.02 mmol) 3-phenylpropiolic acid and 1.17 ml DIPEA in DCE (20 ml) was stirred for 5 h at RT. Subsequently, the reaction solution was washed with water and a sat. aqueous Na2CO3 soln and dried over MgSO4. After filtering and concentration in vacuo, column chromatography (SiO2, chloroform) was performed on the residue, yielding 267 mg (0.86 mmol, 51%) 3-phenyl-N-(1-(thiazol-2-yl)piperidin-4-yl)propiolamide.
