I have done a lot with BOC in THF, works great for me.
In fact, I would often BOC protect just one of the amines on o-phenylenediamine by controlling the stoichiometry. So what I would do is take my o-phenylenediamine in THF is one syringe, and BOC in THF in another syringe, and add them together slowly into THF over ~16 hours with a syringe pump. After protecting the first amine, it made the second amine much less reactive and so my maintaining 1:1 ratio the BOC would react preferentially with a unproteted o-phenylenediamine.
As others have said, you might not have a problem with the OH group (the relative activity depends more on just the functional group, but its local environment as well as solvent, etc). But if you do find you have trouble and you get the OH group reacted as well, you can try controlling the stoichiometry with slow addition.
You can do slow addition with drop adders as well; we did that at first to, and get them dropping enough to add ~50mL solution over ~6 hours. We got higher yield and purity with the syringe pump (though they cost ~$2000, and the gas tight syringes you need in that large size are another ~$400+ each...)
