If you made a compound, got its NMR, and it did not match the "predicted" values, would be spectrum or the predictions be in error? The spectrum is always correct. Sometimes, you may have to adjust your structure though (probably not in this case). Since the chemical shift can vary quite widely, I am reluctant to say, it is now too wide, especially if you can verify its identity by D2O exchange.
Since CDCl3 seems as though it is loaded with HCl (or DCl), the stoichiometry of the acid-base reaction may change depending on the amount of amine being neutralized. If you want to shift everything, run the spectrum in d6-DMSO.
