E2 towards secondary over tertiary and primary beta-carbons

I would like to convert this tertiary bromoalkane to this trisubstituted alkene via E2

Theoretically, using a strong base (NaOH) would result in the formation of the Zaistev product (tetrasubstituted) as major, which I do not want.

If instead I use a sterically hindered base such as t-BuOK I would get the Hofmann product (disubstituted), which I also do not want.

What would I need to use in order to obtain the 'intermediate' trisubstituted alkene? Would it work if I just used a base that's less sterically hindered than t-BuOK but still blocks formation of Zaistev? Like NaOEt for example?


Thank you
