Reaction Steps

To a solution of (S)-Piperidine-2-carboxylic acid (5-tert-butyl-isoxazol-3-yl) amide; hydrochloride (110 mg; 0.382 mmol) in DMF (1.5 mL) is added 4-chlorobenzenesulfonyl chloride (80.6 mg; 0.382 mmol) and N,N-diisopropylethylamine (0.133 mL; 0.764 mmol). The reaction mixture is left stirring at room temperature for 18 hours in the presence of catalytic amount of 4-dimethylaminopyridine. The reaction mixture is quenched with water and extracted with ethyl acetate twice. The combined organics are washed with water then brine, dried over Na2SO4, filtered and concentrated in vacuo. Purification by flash chromatography on silica gel using ethyl acetate/Hexanes provides the title compound, m/z 426 [M+H+].
