Reaction Steps
The 3-(3-methoxy-phenyl)-3-oxo-propionic acid was prepared from 3-methoxybenzoyl chloride (10.3 g, 60.4 mmol) and bis(trimethylsilyl)malonate (16.2 mL, 63.4 mmol) with Et3N (17.7 mL, 127 mmol) and LiBr (5.77 g, 66.4 mmol) in CH3CN at 0° C. according to general procedure H (method c1). The crude material (6.38 g) was transformed into the title compound by stirring in isopropenyl acetate and conc. H2SO4 according to general procedure J (method a). Obtained as a yellow oil (640 mg).
