  Chemistry Development of a Convergent Route to Trecetilide Hemi-Fumarate

  摘要：

  A novel, efficient, stereoselective synthetic route for N-(4-{4-[ethyl(6-fluoro -6-methylheptyl)amino]-1-(S)-hyd roxybutyl}-phenyl)methanesulfonamide hemi-fumaric acid salt (trecetilide hemi-fumarate, Figure 1) has been developed. The process features a convergent approach, which assembles two key intermediates in the last step to form the final molecule, which is then isolated by pH-controlled extraction. The new route offers significant yield and purity advantages over the previous route. However, the solvent volume and cycle time were not fully optimized due to the termination of the project.

  A process for preparing (S)-(−)-N-[4-[4-[ethyl(6-fluoro-6-methylheptyl)amino]-1-hydroxylphenyl]methanesulfonamide hemifumarate salt, which comprises reacting N-[4-[(2S)-tetrahydro-5-hydroxy-2-furanyl]phenyl]methanesulfonamide(IIa) with fluoroamine (III) in the presence of triacetoxyborohydride and ethyl acetate to provide [4-[-4-[ethyl(6-fluoro-6-methylheptyl)amino]-1-hydroxylphenyl]methanesulfonamide(I) and then converting I into the hemifumarate salt Ia. A process for preparing IIa is also claimed as well as intermediates IIa-IId.
