Published in 2025 at "RSC Advances"

DOI: 10.1039/d5ra06779k

Abstract: This study presents an optimized synthetic pathway for suvorexant and establishes a robust method for the simultaneous determination of residual solvents. The synthesis commenced with chiral precursors, specifically (R)-3-(BOC-amino)butyric acid and N-benzyl glycine ethyl ester,… read more here.
