66% | With O-(1H-benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate; N-ethyl-N,N-diisopropylamine; In chloroform; at 20℃; for 16.0h; | First Step Synthesis of N-(1-Azabicyclo[2.2.2]oct-3(R)-yl)furo[2,3-c]pyridine-5-carboxamide To a solution (10 mL) of <strong>[478148-62-8]furo[2,3-c]pyridine-5-carboxylic acid</strong> (0.16 g, 1.0 mmol) in chloroform, o-(benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate (0.57 g, 1.5 mmol), diisopropylethylamine (0.70 mL, 4.0 mmol), and (R)-quinuclidine-3-amine hydrochloride (0.20 g, 1.0 mmol) were added, and the resulting mixture was stirred at room temperature. Sixteen hours later, distilled water was added thereto, and the resultant was then extracted with chloroform. The organic layer was washed with brine, then dried over anhydrous sodium sulfate and concentrated. The obtained crude product was purified by silica gel column chromatography (amine silica gel DM1020, Fuji Silysia Chemical Ltd., chloroform alone to chloroform/methanol=98/2) to obtain the title compound (0.18 mg; 66%) as a colorless liquid. 1H-NMR (400 MHz, CDCl3) delta: 1.40-1.55 (1H, m), 1.65-1.74 (2H, m), 1.80-1.90 (1H, m), 2.02-2.06 (1H, m), 2.63-2.70 (1H, m), 2.75-3.00 (4H, m), 3.39-3.46 (1H, m), 4.12-4.20 (1H, m), 6.89-6.92 (1H, m), 7.80 (1H, d, J=2.0 Hz) 8.25-8.35 (1H, m), 8.46-8.49 (1H, m), 8.75-8.78 (1H, m).MS (ESI) [M+H]+272 |
