API Intermediate Description: 2‑Bromo‑5‑methylbenzoic acid is used in the synthesis of Filorexant (MK‑6096), a dual orexin receptor antagonist that was developed for the treatment of insomnia. In reported synthetic methodology, 2‑bromo‑5‑methylbenzoic acid is coupled with a pyrimidine derivative (such as 2‑chloropyrimidine) using palladium‑catalyzed cross‑coupling (e.g., Negishi coupling) to form 5‑methyl‑2‑(pyrimidin‑2‑yl)benzoic acid, which is an important molecular fragment incorporated into the Filorexant API’s structure.
