Versuchsvorschrift

A solution of (S)-perhydro-azepine-2-carboxylic acid (5-tert-butyl-isoxazol-3-yl)-amide hydrochloride (0.30 g, 1.13 mmol), DIPEA (0.32 g, 2.48 mmol) and DMAP (16.0 mg, 0.13 mmol) is stirred at room temperature for 15 minutes. 1,1-Dioxo-1λ6-thiomorpholine-4-carbonyl chloride (0.27 g, 1.35 mmol) (prepared according to method M step 1) is added drop wise at 0° C. to the reaction mixture that is slowly warmed up to room temperature and stirred for 14 hours. The reaction mixture is diluted with EtOAc, washed with water and brine. After drying the organic phase over anhydrous Na2SO4, removal of the solvent under reduced pressured affords the crude product that is purified by prep TLC to afford the title product; m/z 427 [M+H+].
