Versuchsvorschrift

To a solution of 3-phenyl-3-(3-trifluoromethyl-benzenesulfonylamino)-propionic acid (100 mg, 0.268 mmol, 1.0 eq) and DMF (one small drop) in CH2Cl2 (2.5 mL) was added oxalyl chloride (68 mg, 0.536 mmol, 2.0 eq). The reaction was stirred at 0° C. for 1 h. It was warmed to RT and stirred at RT for additional 15 min. Solvent was removed with a rotary evaporator. The newly formed acid chloride was dissolved in CH2Cl2 (2 mL) and the solution was cooled down to 0° C. A solution of methyl-(7-piperidin-1-ylmethyl-chroman-4-yl)-amine (70 mg, 0.268 mmol, 1.0 eq) in CH2Cl2 (0.95 mL) was added slowly. The resulting mixture was stirred at 0° C. for 20 min. The mixture was warmed to RT and stirred at this temperature for additional 20 min. The reaction was quenched with saturated Na2CO3 (60 mL) The crude was extracted with CH2Cl2 (60 mL×3). The extract phase was washed with saturated NaCl, dried over Na2SO4, filtered and concentrated. Flash column chromatography (silica gel, 0-4% MeOH—CH2Cl2) afforded the title compound as a colorless thin film. MS (ESI, pos. ion) m/z: 616 (M+1).
