Reaction Steps
To a solution of (5Z)-4-(prop-2-yn-1-ylamino)-5-(piperidin-4-ylmethylidene)-1,3-thiazol-2(5H)-one dihydrochloride (200 mg) in DMF (3 mL) were added N-ethyl-N-(1-methylethyl)propan-2-amine (0.56 mL), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (283 mg), and 5-chlorobenzofuran-2-carboxylic acid (151 mg). The reaction mixture was stirred at room temperature overnight, water was added, the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was recrystallized from ethyl acetate/heptane to give the title compound (57 mg).
