反応手順

To a solution of ethyl 3-(4-hydroxyphenyl)-2-methylpropanoate (672) (150 mg, 0.72 mmol), potassium carbonate (149.3 mg, 1.08 mmol) in toluene (7 mL) was added N,N-dimethylmethylideneammonium iodide (173.2 mg, 0.94 mmol) and stirred for 72 hours. Water was added and the reaction was extracted with ethyl acetate and the combined organic layers dried over sodium sulfate, filtered and concentrated in vacuo. The crude compound was purified by flash column chromatography on silica gel with hexanes and EtOAc (50%) to give ethyl 3-(3-((dimethylamino)methyl)-4-hydroxyphenyl)-2-methylpropanoate (673).
