专利号:WO-2025215126-A1 优先权日:2024-04-12 标题:Synthesis of vidofludimus and its calcium salt 发明人:VITT DANIEL; IGLICAR PETRA; GEGE CHRISTIAN; Mühler Andreas; KOHLHOF HELLA; GRÖPPEL MANFRED 权利人:IMMUNIC AG 摘要:The invention relates to the process of preparation of 2-fluoro-4-(3-methoxyphenyl)aniline (3) as an intermediate. Said intermediate 2-fluoro-4-(3-methoxyphenyl)aniline (3) is obtained in a Suzuki coupling reaction from (3-methoxyphenyl)boronic acid (1) and 4-bromo-2-fluoro-aniline (2). The invention further relates to the synthesis of vidofludimus (5) from said intermediate 2-fluoro-4-(3-methoxy-phenyl)aniline (3) and from 1-cyclopentene-1,2-dicarboxylic anhydride (4). The invention further relates to the synthesis of vidofludimus calcium (6) from said vidofludimus (5) and from a calcium salt, preferably Ca(OH)2.
