Reaction Steps
Dissolve 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (3.57 g, 18.62 mmol), 4-(dimethylamino)pryidine (463.8 mg, 3.79 mmol) and adipic acid monomethyl ester (2.97 g, 18.55 mmol) in 100 mL of CH2Cl2 and allow it to stir at room temperature for 45 minutes. Add crude 2-amino-1-(2-methoxy-phenyl)-ethanone hydrochloride (3.74 g, 18.55 mmol) and triethylamine (3.75 g, 37.1 mmol) to the reaction mixture and allow it to stir at ambient temperature for 22 hours. Dilute the reaction with 200 mL of CH2Cl2 and wash it with 1 N HCl (2×), saturated aqueous NaHCO3 (2×) and brine (1×). Dry the organic layer with MgSO4. Filter the drying agent and concentrate in vacuo to afford 4.57 g of the titled product (80%): mass spectrum: m/z=308.1 (M+H).
