Reaction Steps
To 2-(3-Benzyloxy-phenyl)-3-oxo-succinic acid diethyl ester (1.28 g, 3.6 mmol) in water (5 ml) was added formaldehyde (600 uL, 37% solution, 6.6 mmol) and potassium carbonate (0.37 g, 2.7 mmol). The reaction was stirred vigorously overnight The organic products were extracted into diethyl ether which was dried (MgSO4), and evaporated. The residue was purified by column chromatography over silica gel (silica gel 60, EM Science) using 5% ethyl acetate:hexane as eluent to afford 0.99 g (55% yield) of the title compound as an oil. 1H NMR (CDCl3, 400 MHz) δ 7.48-7.27 (m, 6H), 7.10-6.97 (m, 3H), 6.35 (s, 1H), 5.90 (s, 1H), 5.10 (s, 2H), 4.30 (q, J=7.2 Hz, 2H), 1.36 (t, J=7.2 Hz, 3H).
