Abstract
Some synthetic methods of 1 bromo 3,4,5 trimethoxybenzene BTMOB are compared.One can obtain good yield by Sandmeyer reaction after 3,4,5 trimethoxyaniline is diazotized.The optimum reaction conditions are determined:n(ArNH 2)∶ n (NaNO 2)∶ n (NaBr)=1 0∶1 2∶1 5,temperature of diazotization below 5 ℃ and the complex of diazonium salt refluxed for 1 h during decomposition.Yield of BTMOB is about 87 5%.
