(式中、R1がヒドロキシメチル基、R2がフェニル基、R3がヒドロキシ基である一般式(II)の化合物)
2−ヒドロキシ−2−(2−クロロフェニル)酢酸のラセミ体(20.0g、107ミリモル)を水で飽和した酢酸エチル60cm3に溶解し、そこに(1S,2S)−(+)−1−フェニル−2−アミノ−1,3−プロパンジオール(18.0g、107.5ミリモル)を添加し、次いで、室温で(S)−(+)−2−ヒドロキシ−2−(2−クロロフェニル)アセテート、および(1S,2S)−(+)−1−フェニル−2−アミノ−1,3−プロパンジオールから形成された塩を種として添加した。
実施例3で得られた(S)−(+)−2−ヒドロキシ−2−(2−クロロフェニル)酢酸に富む13.5gのエナンチオマー混合物を24cm3の水に溶解し、11.56g(289ミリモル)の水酸化ナトリウムでアルカリ化し、2.4cm3のジメチルスルホキシドを加え、混合物を100℃で5時間攪拌した。得られた反応混合物を20cm3の水で希釈し、24.3cm3の37%塩酸(289ミリモル)で酸性化し、メチル−t−ブチルエーテルで抽出した。
