The present invention relates to production of 2-cyclohexyl-2-hydroxy-2-phenylacetic acid useful as an intermediate for pharmaceutical products, by an industrial means, economically, safely in a good yield. Novel 2-(2′-cyclohexen-1′-yl)-2-hydroxy-2-phenylacetic acid ester obtained by reacting cyclohexene and benzoylformic acid ester in the presence of a Lewis acid is hydrolyzed and reduced to give 2-cyclohexyl-2-hydroxy-2-phenylacetic acid.
本发明涉及通过工业手段,经济、安全地以高产率生产用作制药产品中间体的2-环己基-2-羟基-2-苯乙酸。通过在Lewis酸存在下将环己烯和苯甲酰甲酸酯反应得到的新型2-(2′-环己烯-1′-基)-2-羟基-2-苯乙酸酯被水解和还原以得到2-环己基-2-羟基-2-苯乙酸。
