Abstract

Представляются новые способы получения кристаллических форм А и В илапразола и превращения указанных кристаллических форм. Указанные новые способы включают способ получения кристаллической формы А высокой чистоты путём получения неорганической соли илапразола или её гидрата и последующей нейтрализации полученной неорганической соли илапразола или её гидрата с помощью кислоты в органическом растворителе (индивидуальном растворителе или в смеси растворителей); способ получения кристаллической формы В высокой чистоты путём удаления примесей из илапразола с использованием органического растворителя (индивидуального растворителя или смеси растворителей); и способ превращения кристаллической формы А в кристаллическую форму В или кристаллической формы В в кристаллическую форму А.New methods of obtaining crystalline forms A and B of ilaprazole and converting said crystalline forms are presented. These new methods include a method for obtaining high purity crystalline form A by obtaining an inorganic salt of ilaprazole or its hydrate and then neutralizing the resulting inorganic salt of ilaprazole or its hydrate with an acid in an organic solvent (an individual solvent or in a mixture of solvents); a method of obtaining a crystalline form B of high purity by removing impurities from ilaprazole using an organic solvent (an individual solvent or a mixture of solvents); and a method of converting crystal form A to crystal form B or crystal form B to crystal form A.
