Versuchsvorschrift

4-(6-Chloro-4-(ethoxycarbonyl) chroman-7-yloxy)benzoic acid (Preparation 1) (67 mg, 0.18 mmol) was diluted with DCM (1 mL) followed by the addition of oxalyl chloride in DCM (2M) (98 μl, 0.20 mmol) and DMF (1 drop). After stirring for 10 minutes, 3-(4-chlorophenyl)propan-1-amine (33 mg, 0.20 mmol) and DIEA (68 μl, 0.39 mmol) were added and the reaction was stirred at ambient temperature for 2 hours. The reaction was loaded directly onto a biotage 25 cartridge and eluted with 5% ethyl acetate/hexanes to 75% ethyl acetate/hexanes to yield ethyl 6-chloro-7-(4-(3-(4-chlorophenyl)propylcarbamoyl)phenoxy)chroman-4-carboxylate (80 mg, 0.15 mmol, 85% yield).
