실험 절차

A solution of hexahydro-pyrrolo[3,4-c]pyrrole-2-carboxylic acid amide hydrochloride in 50% CH2Cl2/CH3OH was treated with DOWEX Monosphere 550A (OH) anion-exchange resin to afford the free base. The DOWEX resin was filtered and the resulting solution was concentrated and used without further purification. To a solution of this hexahydro-pyrrolo[3,4-c]pyrrole-2-carboxylic acid amide (85 mg, 0.54 mmol) and K2CO3 (116 mg, 0.84 mmol) in tert-amyl alcohol (2.6 mL) was added 2-[4-(2-methanesulfonyl-ethyl)-phenoxy]-6-methyl-benzothiazole (120 mg, 0.34 mmol). The reaction mixture was heated to 80° C. for 16 h. The reaction mixture was filtered and washed with CH3OH. The resulting liquid was purified by preparative reverse phase HPLC to afford the title compound (11 mg, 5%). MS (ESI): mass calcd. for C23H26N4O2S, 422.55; m/z found, 423.2 [M+H]+. 1H NMR (500 MHz, CDCl3): 7.62 (d, J=8.3 Hz, 1H), 7.48 (s, 1H), 7.28 (s, 4H), 7.20 (dd, J=8.3, 1.1 Hz, 1H), 4.39 (s, 2H), 3.60 (dd, J=10.2, 8.2 Hz, 2H), 3.30 (dd, J=10.0, 1.9 Hz, 2H), 2.98-2.87 (m, 2H), 2.86-2.80 (m, 2H), 2.76 (dd, J=9.3, 6.9 Hz, 2H), 2.74-2.67 (m, 2H), 2.53 (dd, J=9.3, 3.4 Hz, 2H), 2.45 (s, 3H).
