YieldReaction ConditionsOperation in experiment
82% With (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; caesium carbonate; In tetrahydrofuran; N,N-dimethyl-formamide; at 20 - 90℃; for 1.0h;Inert atmosphere; Sealed tube; [0665] A 3-necked 250 mL round-bottomed flask was charged with cesium carbonate (22.64 g, 69.5 mmol), 2-amino-3-chloropyrazine (3 g, 23.16 mmol, Synchem Inc., Elk Grove Village, IL), and {1,1'-bis(diphenylphosphino)ferrocene} dichloropalladium(II) (1.69 g, 2.32 mmol, Strem Chemicals, Newburyport, MA). A reflux condenser was attached, and the apparatus was sealed. The vessel was evacuated and backfilled with nitrogen. DMF (66.2 mL) was added, followed by triethylborane (1.0 M in THF; 42 mL, 42 mmol; Sigma-Aldrich Corporation, St. Louis, MO, USA). The reaction was then stirred in a pre-heated 90 C oil bath for 1 h. The reaction mixture was cooled to rt, water was added, and the resulting mixture was extracted with DCM (2). The combined extracts were dried over MgSO4 and concentrated in vacuo. The crude residue was taken up in MeOH and loaded onto a column composed of Si- propylsulfonic acid (Silicyle). The column was flushed with 4 column volumes of MeOH before eluting the title compound with 4 column volumes of 2M ammonia in MeOH. The filtrate was concentrated in vacuo, and the residue was purified by silica gel chromatography (eluent: 0-20% 2 M NH3 in MeOH/DCM) to provide 3-ethylpyrazin-2-amine (Intermediate I- 19, 2.34 g, 19.0 mmol, 82 % yield) as a brown oil. 1H NMR (400 MHz, DMSO-d6) d ppm 7.75 (d, J=2.70 Hz, 1H) 7.65 (d, J=2.70 Hz, 1H) 6.13 (br s, 2 H) 2.60 (q, J=7.39 Hz, 2 H) 1.17 (t, J=7.46 Hz, 3 H).
