  Development of an Efficient Large-Scale Synthesis for a 4H-imidazo[5,1-c][1,4]benzoxazine-3-carboxamide Derivative for Depression and Anxiety

  摘要：

  The development and scale-up of an optimized synthesis for a novel drug candidate for depression and anxiety is presented. The updated synthesis represents a convergent and efficient four-stage approach to the API, overcoming high cost of goods (COG), general lack of convergence, and low yield of previous routes. A lower cost of goods resulted from using 3-nitrosalicylaldehyde as a starting material and introducing the expensive side chain (2-methyl-5-(piperazin-1-yl)quinoline) at a later stage. Green chemistry principles were applied when a direct amidation enabled a straightforward conversion of the 4H-imidazo[5,1-c][1,4]benzoxazine-3-carboxylate to the corresponding amide in the last step. In addition, the total number of stages was reduced from seven to four, and solvent usage was greatly minimized. The modified synthesis NUS demonstrated on a kilogram pilot scale, allowing the isolation of the API in 17% overall yield with the required purity.

  Bioisoteric replacement of the metabolically labile N-methyl amide group of a series of benzoxazinones with small heterocyclic rings has led to novel series of fused tricyclic benzoxazines which are potent 5-HT1A/B/D receptor antagonists with and without concomitant human serotonin transporter (hSerT) activity. Optimizing against multiple parameters in parallel identified 6-2-[4-(2-methyl-5-quinolinyl)-1-piperazinyl]ethyl}-4H-imidazo[5,1-c][1,4]benzoxazine-3-carboxamide (GSK588045) as a potent 5-HT1A/B/D receptor antagonist with a high degree of selectivity over human ether-a-go-go related gene (hERG) potassium channels, favorable pharmacokinetics, and excellent activity in vivo in rodent pharmacodynamic (PD) models. On the basis of its outstanding overall profile, this compound was progressed as a clinical candidate with the ultimate aim to assess its potential as a faster acting antidepressant/anxiolytic with reduced side-effect burden.
