Reaction Steps

A mixture of 2-fluorocinnamic acid (0.5 mmol), (±)-1-(3,4-dihydro-2H-benzo[1,4]oxazin-6-yl)ethylamine, Preparation 13 (28.5 mg, 0.16 mmol), EDC hydrochloride (192 mg, 1 mmol), DMAP (61 mg, 0.5 mmol), and triethylamine (202 mg, 2 mmol) in CH2Cl2 was stirred for 3 days. The reaction mixture was directly subjected to purification by flash column chromatography on silica using EtOAc/Hexane (8:1) to provide the desired product (149 mg).
