Is this a gramatically correct sentene?

"The matter could've already been dealt with by the time it took you to say that."
それを言いかかった時間の間に問題はもう扱えていた。

About the 言いかかる. I've never used Japanese grammar like this before and I just need to know if it's possible. Also, while the second half sounds good to me, I want to make sure if it's grammatically correct. If it's not, how would I otherwise say this sentence?
