Participants

Reaction Steps

To a stirred solution of 4-(6-chloro-4-(ethoxycarbonyl)chroman-7-yloxy)benzoic acid (Preparation 1) (75 mg, 0.20 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N,N′-tetramethyluronium hexafluorophosphate (84 mg, 0.22 mmol) in N,N-dimethylformamide (1 mL) at ambient temperature was added phenethylamine (28 μL, 0.22 mmol) and N,N-diisopropylethylamine (105 μL, 0.60 mmol). The resulting yellow solution was stirred at ambient temperature for 1 hour. The reaction mixture was diluted with water (10 mL) and extracted with ethyl acetate (10 mL). The organic layer was washed with brine (5 mL), then dried over sodium sulfate and concentrated to afford ethyl 6-chloro-7-(4-(phenethylcarbamoyl)phenoxy)chroman-4-carboxylate as an off-white solid (89 mg, 93% yield).
