Have you tried a dictionary? A dictionary will list not only definitions but also parts of speech.
The phrase you heard may have been 'pursuant to'.
However, in your sentence, the word is not used correctly, so are you certain that's the actual word you heard?
From your partial example, it sounds like you may have misheard something like 'he did not want to pursue any (some word beginning with the letter 't')'
Pursuant and pursue are different (although related) words.
