Production method of Dehista Chlorpheniramine Maleate

By 2-chlorobenzyl pyridine obtained by two-step condensation. In a dry reaction pot, add sodium ammonia and anhydrous toluene, heat to reflux, and drop 2-p-chlorobenzylpyridine and bromoacetaldehyde diethyl acetal simultaneously. After the addition was completed, the reaction was refluxed for 8h. After cooling and standing, the toluene solution was taken, and the solid was dissolved in a small amount of water and extracted with toluene. The extract was combined with the toluene solution, washed with water until neutral, and the toluene was recovered to obtain 3-p-chlorobenzene-3-(2-pyridyl)-propionaldehyde diethyl acetal. It was mixed with DMF and added to the reaction pot, and the mixed solution of formic acid and water was added under stirring. Heated to 110-120°C for 2h, and 150-160°C for 3h. Cool, recover DMF under reduced pressure, dilute with heating water, and adjust pH to 14 with lye. Then extract with toluene, wash the extract with water until neutral, recover toluene, then distill under reduced pressure, collect fractions at 150-190° C. to obtain cDehista Chlorpheniramine Maleate.
