実験手順
Under stirring, while maintaining the temperature between about 22° C. and about 25° C. with a water bath, 286 g (2.825 mol) of aqueous hydrogen chloride (36%) are dropped on 5063 g (2.379 mol) of Atomoxetine base in a solution of n-butyl acetate, prepared as described in U.S. Provisional Applications Nos. 60/583643, 60/583644, and 60/622065. The hydrochloride crystallized. The resulting suspension is stirred at about 25° C. for about one hour, and the solid is collected by filtration, and washed three times with 900 ml of n-butyl acetate. About 850 g of wet Atomoxetine Hydrochloride are obtained. After two separate preparations, samples of obtained wet solids are dissolved in water (2 g in 100 ml). The pH determined for each sample is 2.39 and pH 2.40, respectively.
