Procedure
4-(6-chloro-4-(ethoxycarbonyl)chroman-7-yloxy)benzoic acid (Preparation 1) (51.5 mg, 0.137 mmol), in 1:1 DMF:DCM (0.1 M) was sequentially treated with 3,4-dichlorobenzylamine (26.5 mg, 0.150 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (31.4 mg, 0.164 mmol), and 1-Hydroxy-7-azabenzotriazole (5.58 mg, 0.0410 mmol) at ambient temperature. After 16 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 (69.0 mg, 0.129 mmol, 94.4% yield) as a white solid.
Workup
