Potassium Carbonate → Tert-butyl-7-[(2-phenyl-5-methyl-1,3-oxazol-4-yl)methoxy]chromane-3-carboxylate

Participants

Reaction Steps

To a stirred solution of 4-(chloromethyl)-5-methyl-2-phenyl-1,3-oxazole (103.5 mg, 0.5 mmol) and potassium carbonate (138.4 mg, 1 mmol), tert-butyl 7-hydroxychromane-3-carboxylate (125 mg, 0.5 mmol) was added and the reaction mixture was stirred at room temperature for 48 hrs. Water (50 ml) was added and the precipitated product was extracted with 25 ml of diethyl ether. Ether layer was washed with water (25 ml) twice and dried. On evaporation of solvent, the product was obtained as pale yellow gum (150 mg, 36%).
