PROCEDURE

实验过程

2-(4-Methylphenyl)-4'-[(2-methyl-1,4,5,6-tetrahydroimidazo[4,5-d][1]benzazepin-6-yl)carbonyl]benzanilide was dissolved in 10 ml of ethyl alcohol, the resulting solution was mixed with 0.37 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 500 mg of 2-(4-methylphenyl)-4'-[(2-methyl-1,4,5,6-tetrahydroimidazo[4,5-d][1]benzazepin-6-yl)carbonyl]benzanilide hydrochloride (Example 19(2)).
