Procedure
A mixture of 2,4-difluorocinnamic acid (0.5 mmol), (±)-5-(1-aminoethyl)-2,3-dihydro-indole-1-carboxylic acid, methyl ester, Preparation 20 (132 mg, 0.6 mmole), EDC hydrochloride (192 mg, 1.0 mmole), DMAP (61 mg, 0.5 mmole), and triethylamine (202 mg, 2 mmole) in CH2Cl2 (8 mL) was stirred at room temperature for 16 hours. Water was added, the aqueous layer was extracted with dichloromethane, and the combined organic layers were washed with brine, dried over magnesium sulfate, and evaporated in vacuo. The crude product was purified by flash column chromatography on silica eluting with EtOAc/hexane (7:3) to give the title compound (125 mg) as a solid.
