2-(4-Amino-3-methylphenoxy)ethan-1-ol → Ethyl 2-{[4-(2-hydroxyethoxy)-2-methylphenyl]amino}-4-oxo-4,5-dihydrofuran-3-carboxylate

Participants

Reaction Steps

A solution of 4-(2-hydroxyethoxy)-2-methylaniline (0.69 g, 4.1 mmol) and ethyl 2-ethoxy-4-oxo-4,5-dihydrofuran-3-carboxylate (0.83 g, 4.2 mmol) in ethanol (8.3 mL) was stirred at ambient temperature for 16 h. The solvent was removed under reduced pressure, and ethanol was added to precipitate the product. The precipitate was collected by filtration then dried to afford ethyl 2-{[4-(2-hydroxyethoxy)-2-methylphenyl]amino}-4-oxo-4,5-dihydrofuran-3-carboxylate as solid (0.55 g, y. 42%).
