Reaction Steps

To a solution of (S)-Azetidine-2-carboxylic acid (5-tert-butyl-isoxazol-3-yl)-amide; hydrochloride (100 mg; 0.385 mmol) in DMF (1 mL) is added n-propylsulfonyl chloride (0.043 mL; 0.385 mmol) and N,N-diisopropylethylamine (0.201 mL; 1.155 mmol). The reaction mixture is left stirring at room temperature for 18 hours. After this time, the reaction mixture is diluted with ethyl acetate and washed with water twice 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 330 [M+H+].
