Substitute solvent for diethyl ether?

I want to run a reaction that needs diethyl ether as anti solvent in the last step (comes from articles).
But I can't use it due to its harmful effects on the body. 
Is there any other solvent?


My reaction is about substitution of $\ce{-OH}$ of lignin with [BiBB](http://www.chemspider.com/Chemical-Structure.80021.html) in THF and in other one in $\ce{EtOAc}$ as solvent. 




It is strange that you are concerned about diethyl ether (which has been used as an anesthetic), but you are not concerned about THF. From the [US Pharmacopoeia](http://www.usp.org/sites/default/files/usp_pdf/EN/USPNF/generalChapter467Current.pdf): 



> 
> Permitted Daily Exposure  
> 
>  Tetrahydrofuran 7.2 mg/day  
> 
>  Diethyl Ether 50 mg/day  
> 
>  Ethyl Acetate 50 mg/day

If you dry the product thoroughly (above 120°C), you should not have any problems with residual solvents.
