Procedure

4-(6-Chloro-4-(ethoxycarbonyl)chroman-7-yloxy)benzoic acid (Preparation 1) (48.8 mg, 0.130 mmol), in 1:1 DCM:DMF (0.1 M) was sequentially treated with 2-(3-chlorophenyl)ethylamine (22.2 mg, 0.143 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (29.8 mg, 0.155 mmol), and 1-hydroxy-7-azabenzotriazole (5.29 mg, 0.0389 mmol) at ambient temperature. After 48 hours the reaction was applied directly to a silica gel column and eluted with a gradient (15% to 60%) of ethyl acetate-hexanes to provide the title compound (61.1 mg, 0.119 mmol, 91.7% yield) as a white solid.
