Abstract
4-[trans-4-(Hydroxymethyl)cyclohexyl]phenol (EGX358) is a potent and highly selective estrogen receptor beta (ERβ) agonist which has demonstrated efficacy for moderation of a chemically induced hot flash and for memory consolidation in an ovariectomized mouse model for menopause. An improved synthetic route to EGX358 is reported which proceeds in four steps and which is chromatography-free.
