実験手順

To a cold slurry of (S)-1-(4-Chloro-phenyl)-6-oxo-piperidine-2-carboxylic acid (0.2 g; 0.788 mmol) and 5-amino-3-tert-butylisoxazole (0.110 g; 0.788 mmol) in pyridine (0.956 mL; 11.820 mmol) is added phosphorous oxychloride (0.088 mL; 0.946 mmol). The mixture is stirred at 0° C. for 30 minutes and then diluted with water and extracted with ethyl acetate several times. The organics are combined and washed with water and brine, dried (Na2SO4), filtered and concentrated in vacuo. Purification by preparative HPLC affords title compound, m/z 376 [M+H+].
