Abstract
Starting with 3,4-methylenedioxy aniline, the intermediate 3,4-methylenedioxy bromobenzene was obtained through Sandmeyer reaction (the yield was 75.0%), then the objective product 3,4-methylenedioxy phenethylamine was prepared with Grignard reaction (the yield was 74.8%), esterification (the yield was 94.0%) and Gabriel reaction (the yield was 63.0%). Finally the structure of product was characterized by IR spectrum and liquid chromatograph-mass spectrometer (LC-MS). The effects of temperature on the each reaction were discussed, and the optimum reaction condition was determined.
