The subject of the invention is a novel process for the preparation of N-[2-n-butyl-3-4-[(3-di-n-butylamino)- propoxy]benzoyl}benzofuran-5-yl]-methanesulfonamide of formula (I), and pharmaceutically acceptable salts thereof characterized in that, the acyl group of the benzofuran derivative of the general formula (II), where R represents C 1-4 alkyl-, C1-4 alkoxy- or aryl group - is selectively cleaved and if desired, the resulting compound of formula I is transformed into its salt.
该发明涉及一种新型制备N-[2-正丁基-3-4-[(3-二正丁基氨基)丙氧基]苯甲酰}苯并呋喃-5-基]-甲磺酰胺(化学式(I))及其药学上可接受的盐的过程,其特点在于,将一般式(II)中苯并呋喃衍生物的酰基,其中R代表C1-4烷基、C1-4烷氧基或芳基,选择性地裂解,并如有需要,将化合物转化为其盐形式。
