• Convergent Kilogram-Scale Synthesis of Dual Orexin Receptor Antagonist

  MK-6096 is an orexin receptor antagonist in clinical trials for the treatment of insomnia. Herein we describe its first kilogram-scale synthesis. Chirality on the a-methylpiperidine core was introduced in a biocatalytic transamination using a three-enzyme system with excellent enantioselectivity (>99% ee). Low diastereoselectivity of the lactam reduction was overcome by development of a camphor sulfonic acid salt formation and dr upgrade. A chemoselective O-alkylation with 5-fluoro-2-hydroxypyridine was optimized and developed. Overall, 1.2 kg of MK-6069 was prepared in nine steps and 13% overall yield.
