Procedure

A solution of acetic acid 4-formyl-2,6-dimethoxy-phenyl ester (25 mmol) in MeOH (100 mL) was treated with NaBH4 (1 equiv.) at 0° C. for 15 min. After quenching with acetone and evaporating the solvent, work-up (CH2Cl2) and evaporation gave the title compound as a white solid (85% yield). Rf (in EtOAc/Hexane 1:1): 0.5. 1H-NMR (CDCl3): δ 6.66 (s, 1H), 4.68–4.70 (d, 2H), 3.85 (s, 3H), 2.36 (s, 3H), 1.74 (t, 1H).
