実験手順

To a stirred solution of 2-[4-(hexahydro-pyrrolo[3,4-b]pyrrol-5-ylmethyl)-phenoxy]-benzothiazole hydrochloride (100 mg, 0.26 mmol) and Et3N (215 μL, 1.6 mmol) in CH2Cl2 (2 mL) was added N-Boc-glycine (95 mg, 0.5 mmol), and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (104 mg, 0.5 mmol). The resulting solution was then stirred at rt for 16 h. The resulting mixture was then treated with trifluoroacetic acid (1 mL) at rt for 3 h. The crude solid was dissolved in CH3OH/DMSO (2:1) and purified via reverse phase preparative HPLC to yield the title compound as a fluffy white solid (37 mg, 35%). MS (ESI): mass calcd. for C22H24N4O2S, 408.5; m/z found, 409.2 [M+H]+. 1H NMR (500 MHz, CDCl3): 7.74 (d, J=8.1 Hz, 1H), 7.68 (d, J=8.0 Hz, 1H), 7.43-7.33 (m, 3H), 7.33-7.26 (m, 3H), 4.51-4.42 (m, 1H), 4.27-4.19 (m, 0.5H), 4.02-3.92 (m, 0.5H), 3.66 (d, J=13.2 Hz, 1H), 3.58 (d, J=5.0 Hz, 0.5H), 3.51-3.37 (m, 3H), 3.28 (d, J=16.7 Hz, 0.5H), 2.91-2.76 (m, 2H), 2.70-2.60 (m, 1H), 2.58-2.50 (m, 1H), 2.50-2.37 (m, 1H), 2.14-1.96 (m, 1H), 1.97-1.80 (m, 1H).
