Molecular formula:C26H28ClNO
Molecular Weight:405.96

Clomifene, 2-[p-(2-chloro-1,2-diphenylvinyl)phenoxy]triethylamine (28.2.4), is synthesized from 4-hydroxybenzophenone by reacting it with 2-diethylaminoethylchloride in the presence of an alkali, which gives 4-(2-diethylaminoethoxy)benzophenone (28.2.1). This is reacted with benzylmagnesium chloride in a Grignard reaction, forming as a result the corresponding carbinol (28.2.2). Dehydrating this with hydrogen chloride gives 2-[p-(1,2-diphenylvinyl) phenoxy]triethylamine (28.2.4), the vinylic hydrogen atom of which is replaced with a chlorine atom using N-chlorosuccinimide, giving clomifene (28.2.4) .
