Procedure

The above carboxylic acid (0.05 g, 0.091 mmol) was dissolved in anhydrous DMF (2 mL) and benzotriazol-1-yloxytris(pyrrolidino)phosphonium hexafluorophosphate (PyBOP) (0.071 g, 0.137 mmol) was added to the reaction solution. The reaction mixture was stirred at room temperature for 10 min and glycinamide hydrochloride (0.015 g, 0.137 mmol) was added to the mixture followed by N,N-diisopropylethylamine (0.039 mL, 0.227 mmol). The reaction mixture was stirred at room temperature for another 15 min. The mixture was then diluted with EtOAc (10 mL) and washed with water (×2), 1N HCl, saturated NaHCO3 and then water (×1). The organic phase was dried over Na2SO4 and concentrated. The crude product was purified by silica gel preparative thin layer chromatography using CH2Cl2-MeOH (95:5) as an eluent to afford 0.043 g of the title compound as a white foam (M+1, 604.2).
