Reaction Steps
To a mixture of phenol (0.01 mol) and ethyl 2-bromo-2-methylpropanoate (0.01 mol) in acetonitrile was added Cs2CO3 (0.015 mol), and the reaction mixture was refluxed overnight. After removal of the solvent, the residue was partitioned between ethyl acetate and water. The organic layer was washed with 1 N aqueous NaOH solution, water, and brine, and then dried sodium sulfate. Concentration gave the titled compound. 1H NMR (400 MHz, CDCl3) δ ppm 7.21˜7.25 (m, 2H), 6.98 (t, J=7.2 Hz 1H), 6.83˜6.86 (m, 2H), 4.23 (q, J=7.2 Hz 4H), 1.60 (s, 6H), 1.24 (t, J=7.2 Hz 3H); LCMS (ESI+) m/z 209 (M+H)+.
