Procedure

To a round-bottom flask was added with (E)-4-(4,4,4-trifluorobut-1-enyl)piperidin-4-ol (50 mg 0.24 mmol), 4-(benzo[d]thiazole-4-sulfonamido)benzoic acid (80 mg, 0.24 mmol), DIPEA (155 mg, 1.2 mmol), HATU (110 mg, 0.29 mmol), and DCM (5 mL). The mixture was stirred at r.t. for 16 hours. After washing with brine, the combined organic layer was dried over anhy. Na2SO4 and concentrated in vacuo. Purification by a standard method gave the desired compound. 1H NMR (CHLOROFORM-d) δ: 9.31 (s, 1H), 8.19 (d, J=8.1 Hz, 1H), 8.10 (d, J=7.5 Hz, 1H), 7.99 (s, 1H), 7.54 (t, J=7.8 Hz, 1H), 7.17-7.24 (m, J=8.3 Hz, 2H), 7.08-7.15 (m, J=8.1 Hz, 2H), 5.78-5.94 (m, 1H), 5.64-5.76 (m, 1H), 4.28-4.47 (m, 1H), 3.51 (s, 1H), 3.32-3.48 (m, 1H), 3.27 (br. s., 1H), 2.84 (dd, J=10.5, 7.0 Hz, 1H), 1.66 (br. s., 4H), 1.46 (d, J=9.7 Hz, 2H). LC-MS: m/z 526.7 (M+H)+
