실험 절차

To a stirred solution tert-butoxy carbonyl-5-[4-(benzothiazol-2-yloxy)-benzyl]-hexahydro-pyrrolo[3,4-c]pyrrole-2-sulfonic acid amide (108 mg, 0.20 mmol) in CH2Cl2 (5 mL) was added trifluoroacetic acid (1 mL). The homogeneous reaction mixture was allowed to stir overnight at rt. The crude reaction mixture was blown down to dryness and dissolved in CH3OH/DMSO (2:1) and purified via reverse phase preparative HPLC to afford the title compound as fluffy white powder (60 mg, 70%). MS (ESI): mass calcd. for C20H22N4O3S2, 430.6; m/z found, 431.1 [M+H]+; 1H NMR (500 MHz, CD3OD): 7.79 (d, J=8.0 Hz, 1H), 7.67 (d, J=8.1 Hz, 1H), 7.52-7.46 (m, 2H), 7.46-7.39 (m, 1H), 7.37-7.27 (m, 3H), 3.68 (s, 2H), 3.24 (dd, J=9.5, 7.0 Hz, 2H), 3.06 (dd, J=9.4, 2.6 Hz, 2H), 2.93-2.87 (m, 2H), 2.87-2.78 (m, 2H), 2.40 (dd, J=8.5, 3.6 Hz, 2H).
