Processes for preparing (((3aR,6aS)-5-(4,6-dimethylpyrimidin-2-yl)hexahydropyrrolo[3,4-c]pyrrol-2(1H)-yl)(2-fluoro-6-(2H-1,2,3-triazol-2-yl)phenyl)methanone are described, which are useful for commercial manufacturing. Said compound is an orexin receptor modulator and may be useful in pharmaceutical compositions and methods for the treatment of diseased states, disorders, and conditions mediated by orexin activity, such as insomnia and depression.
clinical development as a selective orexin-2 antagonist for the treatment of major depressive disorder with insomnia symptoms. During the investigation of an improved synthesis route, a key (3 + 2) cycloaddition reaction was found to occur only at very high temperatures (>250 °C). An exploratory processdevelopment of such a challenging high-temperature cycloaddition was demonstrated in a continuous flow
