Carbon-14-labeled 6-(4-methanesulfonylphenyl)-5-[4-(2-piperidin-1-yl-ethoxy)phenoxy]naphthalen-2-ol, a novel selective estrogen receptor modulator (SERM) was synthesized. The key component, 6-methoxy-1-tetralone-[carbonyl-14C], was synthesized from 3-(3-methoxyphenyl)-propionic acid via an intra-molecular Friedel–Crafts acylation of 4-(3-methoxyphenyl)butanoic acid-[carboxy-14C]. A palladium catalyzed alpha-keto arylation of 6-methoxy-1-tetralone with 4-methanesulfonyl-phenyl bromide, followed by a sequence of bromination, DDQ dehydrogenation, aryl Ullmann reaction, and demethylation with BBr3 gave the desired product LY2066948-[14C].

合成了碳-14 标记的 6-(4-甲磺酰基苯基)-5-[4-(2-哌啶-1-基乙氧基)苯氧基]萘-2-醇,这是一种新型选择性雌激素受体调节剂(SERM)。其关键成分 6-甲氧基-1-四氢萘酮-[羰基-14C]是由 3-(3-甲氧基苯基)-丙酸通过 4-(3-甲氧基苯基)丁酸-[羧基-14C]的分子内 Friedel-Crafts酰化反应合成的。在钯催化下,6-甲氧基-1-四氢萘酮与 4-甲磺酰基溴化苯发生α-酮芳基化反应,然后依次进行溴化、DDQ 脱氢、芳基乌尔曼反应和用 BBr3 脱甲基化反应,最终得到所需产物 LY2066948-[14C]。Copyright © 2007 John Wiley & Sons, Ltd.
