174 g of B1 was added to 400 g of cyclohexane solvent and control the reaction temperature in between -10 and 0 ° C. then 108 g 12 mol / L of concentrated hydrochloric acid was added dropwise and reacted for 14h . The water and cyclohexane were removed by distillation to obtain 122 g of a light yellow transparent solid C1 , The yield was 99.18% and the purity was 99%.122 g of C1 was added to 220 g of dichloromethane and control the reaction temperature in between -10 and 0 ° C. then added 103g of was added in several batches and reacted for 12h. suction filtration and distillation of dichloromethane to obtain 86.01g of 3-amino-1-propyl methyl ether yield was 99.42%, the purity was 99.19%.
