Versuchsvorschrift

A solution of 4-hydroxy-3-methoxy-benzonitrile (11, 1.5 g, 10 mmol) and diisopropylethylamine (2.7 mL, 15 mmol) in CH2Cl2 (50 mL) was treated with chloromethylmethylether (0.92 mL, 12 mmol) and stirred for 3 h. After diluted with CH2Cl2, the mixture was washed with H2O, dried over MgSO4 and concentrated in vacuo. The residue was purified by flash column chromatography over silica gel using EtOAc:Hex (1:2) as eluant to give 12 as white solid (1.54 g, 80%).
