According to CMOS, “the hyphen connects two things that are intimately related, usually words that function together as a single concept or work together as a joint modifier (e.g., tie-in, toll-free call, two-thirds).”

Are you trying to hyphenate tie-in? Unfortunately it cannot be hyphenated because it only contains one syllable.

As a general rule, compound adjectives that come before a noun are hyphenated (for example, "a coffee-colored tie"), but compound adjectives that come after a noun are not hyphenated ("My tie was coffee colored ").
