Procedure

To a solution of 2-(4-nitrophenyl)-1-(2-thiophene2-ylthiazol-4-yl)ethylamine, 22, (0.41 g, 1 mmol) 3-chlorophenylacetic acid (0.170 g, 1 mmol) and 1-hydroxybenzotriazole (HOBt) (0.070 g, 0.50 mmol) in DMF (5 mL) at 00, is added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDCI) (0.190 g, 1 mmol) followed by triethylamine (0.42 mL, 3 mmol). The mixture is stirred at 0° C. for 30 minutes then at room temperature overnight. The reaction mixture is diluted with water and extracted with EtOAc. The combined organic phase is washed with 1N aqueous HCl, 5% aqueous NaHCO3, water and brine, and dried over Na2SO4. The solvent is removed in vacuo to afford 0.290 g (60% yield) of the desired product which is used without further purification. ESI− MS 482 (M−1).
