実験手順

(R)-2-(3-(piperidin-1-yl)pyrrolidin-1-yl)benzo[d]thiazole-6-carboxylic acid, the product of Example 54 (40 mg, 0.121 mmol), morpholine (12 μL, 0.133 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (51 mg, 0.133 mmol) were combined in dichloromethane (2 mL). Triethyl amine (52 μL, 0.374 mmol) was added and mixture was stirred overnight at room temperature. The mixture was diluted with dichloromethane and washed with a 1 N aqueous sodium hydroxide solution. The organic layer was absorbed on silica gel and the mixture was purified by column chromatography eluting with a gradient of methanol and dichloromethane (2-18%) to afford the title compound. 1H NMR (300 MHz, CDCl3) δ ppm 1.41-1.54 (m, 2 H) 1.59-1.70 (m, 4 H) 1.94-2.12 (m, 1 H) 2.24-2.38 (m, 1 H) 2.39-2.60 (m, 4 H) 2.95-3.11 (m, 1 H) 3.37-3.48 (m, 1 H) 3.49-3.61 (m, 1 H) 3.61-3.80 (m, 9 H) 3.81-3.93 (m, 1 H) 7.33 (dd, J=8.31, 1.87 Hz, 1 H) 7.55 (d, J=8.14 Hz, 1 H) 7.73 (d, J=1.70 Hz, 1 H); MS (ESI+) m/z 401.1 (M+H)+.
