69% | With triethylamine In N,N-dimethyl-formamide at 20℃; for 14 h; | Triethylamine (4.13 g, 3 niL, 40.8 mmol, 4 eq) is added to a solution of 6-chloro- nicotinonitrile (1.38 g, 10 mmol, leq), (S)-2-methyl- piperazine (1.0Og, 10 mmol, leq) in DMF (15 niL), and the resulting solution is stirred at rt for 14 h. A white precipitate of triethylamine hydrochloride forms in the course of the reaction. Water (15 mL) and EtOAc (100 mL) are added, the organic layer is separated, dried over sodium sulfate and concentrated under reduced pressure to a white residue. The solid is further dried under high vacuum to yield the desired product as a white solid (1.4 g, 69percent). 1H NMR (400 MHz, CHLOROFORM-cf) δ ppm 8.38 (s, 1 H), 7.58 (d, J=9.60 Hz, 1 H), 6.59 (d, J=9.09 Hz, 1 H), 4.19 - 4.31 (m, 2 H), 3.08 - 3.15 (m, 1 H), 2.92 - 3.04 (m, 1 H), 2.81 - 2.91 (m, 2 H), 2.57 - 2.65 (m, 1 H), 1.15 (d. J=6.32 Hz, 3 H). |
67% | With potassium carbonate In N,N-dimethyl acetamide at 60℃; for 2 h; | To a stirred solution of (2S)-2-methylpiperazine (0.30 g, 2.1 mmol) in DMA (6 mL), 6-chloropyridine-3-carbonitrile (0.29 g, 2.3 mmol) and K2C03 were added. The resultantreaction mixture was heated to 60 °C for 2 h (TLC indicated complete consumption ofstarting material). The reaction mixture was diluted with cold water (20 mL) and extractedwith EtOAc (3 x 25 mL). The combined organic extracts were washed with cold water (20mL) and brine (2 x 20 mL). The organic layer was separated, dried over Na2S04 andconcentrated under reduced pressure to give the crude residue which was purified by columnchromatography (100-200 silica gel, 10 g, 10percent MeOH-DCM) to furnish 6-[(3S)-3-methylpiperazin-1-yl]pyridine-3-carbonitrile (0.29 g, 67percent) as an off-white solid.LCMS: m/z: 203.4 [M+Ht. |
