as the title says I've tried to synthesis that and I've failed a little
so I wanted to make p cresole, then chlorination

so this is my idea, explained better
but I don't really like it so much
would you tell me another good method?
what I don't really when I have to obtain the p cresol because you obtain the o isomer too, and I don't want this, I want to have it 100% pure, if you know what I mean
and sorry for asking so much

It helps if you get your structure correct. the product you drew is


4,4'-(propane-1,3-diyl)diphenol

You actually want this structure?


4,4'-(butane-1,4-diyl)diphenol

sorry, may fault
I want the second one
I modified

I would expect acid/base reactions between the phenol and carbide to complicate this...

[orgopete]

And polymerization of phenol.

[AndEEDJay]

and finally what is the answer?

[orgopete]

You need protection-deprotection or another route, such as acylation-reduction.

[AndEEDJay]

would you tell me a correct way to synthesis that?
without secondary products, with high yield..
