Procedure
To a solution of succinic anhydride (10 g, 0.1 mol) in CH3CN (200 mL) were added (4-methoxyphenyl)methanol (69.0 g, 0.5 mol) and DMAP (12.2 g, 0.1 mol). The reaction mixture was stirred for 3 h at about 30° C. and then diluted with water (700 mL) The resulting mixture was adjusted to pH=10 with saturated Na2CO3 solution and washed with ethyl acetate (300 mL×4) to remove an excess of (4-methoxyphenyl)methanol. The aqueous phase was adjusted to pH=2 with saturated citric acid solution and then extracted with ethyl acetate (200 mL×2). The combined extracts were dried over anhydrous Na2SO4 and concentrated to give product (21.0 g, 88% yield) as a white solid.
