Potassium Carbonate → 3-{2-[4-(2,6-Dichloro-phenoxy)-phenyl]-morpholin-4-yl}-propionic acid tert-butyl ester

Participants

Reaction Steps

A mixture of 3-[2-(4-hydroxy-phenyl)-morpholin-4-yl]-propionic acid tert-butyl ester (200 mg; 0.65 mmol), 2,6-dichlorofluorobenzene (107.35 mg; 0.65 mmol) and K2CO3 (134.9 mg; 0.98 mmol), in DMF (10 mL) was heated at 100° C., for 2 days. After cooling to RT the mixture was diluted with Et2O and washed with water (3 times). The combined organic layers were dried (Na2SO4), filtered, and concentrated in vacuo. The residue was purified by column chromatography (Et2O) to afford 3-{2-[4-(2,6-dichloro-phenoxy)-phenyl]-morpholin-4-yl}-propionic acid tert-butyl ester: (150.00 mg).
