Procedure
To a round-bottom flask was added 4-(3,3-difluoro-2-methylpropyl)piperidin-4-ol (110 mg 0.57 mmol), 4-(benzo[d]thiazole-4-sulfonamido)benzoic acid (190 mg, 0.57 mmol), DIPEA (367 mg, 2.8 mmol), HATU (261 mg, 0.69 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), 8.20 (d, J=8.1 Hz, 1H), 8.10 (d, J=7.5 Hz, 1H), 7.94 (s, 1H), 7.55 (t, J=7.9 Hz, 1H), 7.20 (d, J=8.5 Hz, 2H), 7.12 (d, J=8.6 Hz, 2H), 5.90-5.61 (m, 1H), 4.36 (s, 1H), 3.57-3.42 (m, 1H), 3.21 (s, 2H), 2.24 (d, J=7.6 Hz, 1H), 2.05 (s, 1H), 1.86-1.77 (m, 2H), 1.36 (dd, J=14.8, 6.3 Hz, 4H), 1.10 (d, J=7.0 Hz, 3H). LC-MS: m/z 510.5 (M+H)+
