18 EXAMPLE 18 4'-[(2-Methyl-1,4,5,6-tetrahydroimidazo[4,5-d][1]benzazepin-6-yl)carbonyl]-2-phenylbenzanilide was dissolved in 5 ml of ethyl alcohol, the resulting solution was mixed with 0.19 ml of 4N hydrochloric acid-ethyl acetate and cooled on an ice bath and then the thus precipitated crystals were collected by filtration and washed with a small volume of ethyl alcohol to obtain 220 mg of 4'-[(2-methyl-1,4,5,6-tetrahydroimidazo[4,5-d][1]benzazepin-6-yl)carbonyl]-2-phenylbenzanilide hydrochloride (Example 18(2)).
41 EXAMPLE 41 This compound was crystallized from 31.5 ml of ethyl alcohol and 27.2 ml of 1N hydrochloric acid to obtain crude crystals (B crystal) of 4'-[(2-methyl-1,4,5,6-tetrahydroimidazo[4,5-d][1]benzazepin-6-yl)carbonyl]-2-phenylbenzanilide hydrochloride. These crystals were suspended in 45 ml of acetonitrile, heated for 30 minutes under reflux, cooled down, collected by filtration and then dried to obtain crude crystals (γ crystal). Thereafter, they were suspended in 26 ml of ethyl alcohol, heated for 30 minutes under reflux, cooled down, collected by filtration and then dried to obtain 1.6 g of 4'-[(2-methyl-1,4,5,6-tetrahydroimidazo[4,5-d][1]benzazepin-6-yl)carbonyl]-2-phenylbenzanilide hydrochloride in the form of crystals (α crystal).

72% With water; potassium carbonate In chloroform for 20h; Reflux; Green chemistry; 7 Example 7 Synthesis of Conivaptan hydrochloride In a 500 mL three-necked flask, 39.7 g of compound 10 (0.08 mol), 3.8 g of acetamidine hydrochloride (0.04 mol),5.5 g of potassium carbonate (0.04 mol) and 0.54 g of distilled water (0.03 mol) were dissolved in 300 ml of chloroform. Reflux reaction 20h, TLC tracking and monitoring until the reaction was complete after the reaction was stopped, cooled to room temperature. Washed three times with (300 ml X 3) of distilled water, taken organic phase,Dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give the crude product. The crude product was dissolved in ethanol, concentrated hydrochloric acid was added in an appropriate amount, and the solid was isolated by freezing. The mixture was suction filtered and dried in vacuo to give a solid. The solid was dissolved in water and extracted with dichloromethane (200 ml × 3). Concentrated and dried under reduced pressure to give 15.4 g The yield is 72%.
