Reaction Steps
A solution of 4-(benzyloxy)-2-isopropoxybenzaldehyde (698) (480 mg, 1.776 mmol) and (carbethoxymethylene)triphenylphosphorane (1.1 eq.) in toluene was heated at 100° C. overnight. The reaction was cooled to room temperature and concentrated in vacuo. The crude material was purified by silica gel chromatography (0-50% EtOAc in hexanes) to afford (E)-ethyl 3-(4-(benzyloxy)-2-isopropoxyphenyl)acrylate (699).
