Reaction Steps

100 g of γ-aminopropyl-2,5-dimethoxybenzene was heated at an oil bathtemperature of 180° C in 830 ml of 48% hydrobromic acid while blowing therein nitrogen gas. After the reaction, the reaction mixture wascooled, and the precipitated crystals were filtered out and dried to obtain88 g of the end product having a melting point of 130° ~ 131° C (yield 69.3%).
