Preparation of : 2,5-Dimethoxybenzaldehyde and Nitromethane (while as solvent)) with small ammonium Acetate, 85 degrees 30 min, can produce 2,5-Dimethoxy-beta-nitrostyrene (Ⅰ), yield is 90%. yield. Add 2,5-Dimethoxy-beta-nitrostyrene into ethanol hydrochloride water solution, at 70 ~ 85°C, and then reduction by adding zinc powder and a small amount of mercury to get 2,5-Dimethoxyphenethylamine hydrochloride (Ⅱ). Then add hydrochloric acid methanol solution to get the salt. Yield is up to 60%.
