Procedure
A mixture of 4-[(5-nitro-1H-indol-1-yl)methyl]benzoic acid (1.78 g, 6.0 mmol), 1-[3-(dimethylamino)propyl-3-ethylcarbodiimide hydrochloride (1.15 g, 6.0 mmol), 1-hydroxybenzotriazole hydrate (0.81 g, 6.0 mmol), and L-phenylalanine ethyl ester hydrochloride (1.38 g, 6.0 mmol) was stirred in CH2Cl2 (150 mL). N-methylmorpholine (3.03 g, 30 mmol) was added and the mixture was stirred at room temperature for 15 h. The mixture was then washed with 0.05 N HCl and water. The resulting solution was dried with MgSO4 and concentrated to give ethyl N-{4-[(5-nitro-1H-indol-1-yl)methyl]benzoyl}-L-phenylalaninate as an off-white solid (2.55 g, 90%): MS (ESI) m/z 472; MS (ESI) m/z 470.
