Procedure
Combined methyl 2-(4-methoxyphenyl)acetate (3.58 mL, 22.20 mmol) and 1,1-dimethoxy-N,N-dimethylmethanamine (11.89 mL, 89 mmol) and heated to 100° C. for 14 h. The reaction was concentrated in vacuo to afford a light yellow oil which was purified by flash chromatography (100 g basic silica using a 5% to 50% EtOAc in heptanes gradient to give the title compound (361 mg, 6.91%) as a colorless oil. MS m/z [M+H]+ 236.1.
