Versuchsvorschrift

To a suspension of 2-(4-chloromethyl-phenoxy)-6-fluoro-benzothiazole (152 mg, 0.52 mmol), hexahydro-pyrrolo[3,4-c]pyrrole-2-carboxylic acid amide, hydrochloride (110 mg, 0.57 mmol) and Cs2CO3 (676 mg, 2.08 mmol) in DMF (1 mL) was stirred at rt overnight. The resultant mixture was filtered and the residue purified via preparative reverse phase HPLC to afford the title compound (15 mg, 7%). MS (ESI): Mass calcd for C21H21N4O2SF, 412.1; m/z found, 413.1 [M+H]+; 1H NMR (400 MHz, CD3OD): 7.64 (dd, J=8.9, 4.7 Hz, 1H), 7.58 (dd, J=8.4, 2.6 Hz, 1H), 7.47 (d, J=8.5 Hz, 2H), 7.33 (d, J=8.5 Hz, 2H), 7.19 (dt, J=9.0, 8.9, 2.6 Hz, 1H), 3.66 (s, 2H), 3.59-3.40 (m, 2H), 3.29-3.27 (m, 2H), 2.97-2.83 (m, 2H), 2.77 (d, J=9.3, 6.8 Hz, 2H), 2.46 (d, J=9.3, 3.6 Hz, 2H).
