4-(Aminomethyl)benzonitrile hydrochloride Use and Manufacturing
In a 200 ml four-neck flask equipped with an agitator, a thermometer, a gas conduit, and a reflux condenser, p-cyanobenzylamine (10.0 g) obtained in Preparation Example 3 was dissolved in ethyl acetate (90.0 g). While the reactor was cooled in a water bath, hydrogen chloride gas was fed into the vapor phase of the reactor while stirring. Immediately after the introduction of hydrogen chloride, heat generation was confirmed, and a white solid was precipitated. After the reaction mixture was cooled to room temperature, the white solid was separated through filtration and dried in a desiccator under vacuum, thereby yielding 12.6 g of p-cyanobenzylamine hydrochloride (yield based on p-cyanobenzylamine: 99percent). Through high-performance liquid chromatographic analysis of the thus-obtained p-cyanobenzylamine hydrochloride, the p-cyanobenzylamine content in the hydrochloride was found to be 77 mass percent. In addition, the hydrogen chloride content in p-cyanobenzylamine hydrochloride was found to be 23 mass percent through anion chromatographic analysis. The thus-obtained p-cyanobenzylamine hydrochloride has a bulk density of 0.3 g/ml.In a 200 ml three-neck flask equipped with an agitator, a thermometer, and a dropping funnel, p-cyanobenzylamine hydrate (32.5 g) obtained in Preparation and water (20.2 g) were placed. Concentrated hydrochloric acid (35 mass percent aqueous solution of hydrogen chloride, hereinafter the same solution was employed) (20.5 g) was added dropwise to the mixture through the dropping funnel under stirring, thereby forming a white solid. The white solid was separated through filtration and dried in a desiccator under vacuum, thereby yielding 24.5 g of p-cyanobenzylamine hydrochloride (yield based on p-cyanobenzylamine hydrate: 75percent).
