Reaction Steps

Tert-butyl 4-bromobenzoate (10.3 g, 40.1 mmol), ethyl N-(diphenylmethylene)glycinate (14.99 g, 56.1 mmol), potassium phosphate (25.5 g, 120 mmol) and bis(tri-t-butylphosphine)palladium(0) (0.409 g, 0.801 mmol) were stirred in toluene (120 mL) at 100° C. under nitrogen for 3 days. Room temperature was attained and the mixture filtered through Celite and concentrated in vacuo. The residue was purified by MPLC to give the desired product as a yellow oil. 1H NMR (DMSO-d6, 600 MHz) δ 7.86 (d, J=7.8 Hz, 2H), 7.58 (m, 2H), 7.51 (m, 3H), 7.48 (d, J=7.8 Hz, 2H), 7.45 (m, 1H), 7.41 (t, J=7.5 Hz, 2H), 7.08 (m, 1H), 5.08 (s, 1H), 4.00 (m, 2H), 1.51 (s, 9H), 1.05 (t, J=6.9 Hz, 3H).
