METHOD FOR PRODUCING AMINOALKOXYCARBOSTYRYL DERIVATIVE

-

Page/Page column 8, (2008/06/13)

PROBLEM TO BE SOLVED: To obtain a high-purity aminoalkoxycarbostyryl derivative by an industrially producible simple operation. SOLUTION: A phthalimidealkoxycarbostyryl derivative is heated in the presence of a basic compound to afford a phthalimidic acid derivative, and then, an acidic compound is added to the phthalimidic acid derivative and these compounds are heated to provide the aminoalkoxycarbostyryl derivative. Crystallization is carried out by adding an organic solvent to the reaction liquid to provide a salt of the aminoalkoxycarbostyryl derivative.
