To a slurry of Pamoic acid (32.4 g) in ethyl acetate (250 mL) in a clean round bottomed flask, Imipramine (85 g, pre-generated from Imipramine hydrochloride -90 g, sodium hydroxide -18 kg in water, 60 -100 mL) solution in ethyl acetate is added maintaining the temperature below 50° C. for 3-4 h.
After complete addition, the reaction mixture is stirred at room temperature for about 12-14 h.
The bright yellow slurry thus obtained is filtered and washed with ethyl acetate (400 mL) and dried to get Imipramine Pamoate (76 g, 96%) as bright yellow crystalline product.
