1-(5-CHLOROPYRIDIN-2-YL)METHANAMINE

A solution of 5-chloropicolinonitrile (3.8 g, 27.43 mmol), conc. HCl (3 mL) and 10percent Pd-C (1.0 g) in ethanol (100 mL) was shaken under a hydrogen atmosphere (40 psi) for 2 h. The reaction mixture was filtered, concentrated and the resulting residue taken up in satd NaHCO3 (50 mL) and extracted with CH2Cl2 (4x25 mL). The combined CH2Cl2 layers were dried (Na2SO4), filtered and concentrated to give the title compound as a yellow oil (2.0 g, 51percent yield). LCMS (M+H) calcd for C6H8ClN2: 143.04; found: 143.07. 1HNMR (500 MHz, CDCl3) ' ppm: 8.56-8.51 (1H, br d), 7.66-7.60 (1H, m), 7.28-7.14 (1H, m), 3.97 (2H, s), 1.72 (2H, s).A solution of 5-chloropicolinonitrile (3.8 g, 27.43 mmol), conc.

HCl (3 mL) and 10percent Pd-C (1.0 g) in ethanol (100 mL) was shaken under a hydrogen atmosphere (40 psi) for 2h. The reaction mixture was filtered, concentrated and the resulting residue taken up in satd NaHCOTo a mixture of A-l (2.00 g, 14.03 mmol) in THF (30 mL) was added TFAA (4.42 g, 21.05 mmol), then the mixture was stirred at 20 °C for 16 hours. The mixture was concentrated and the resulting residue was diluted with 0 (50 mL), and extracted with EtOAc (100 mL x 2). The combined organic phase was washed with sat. Na2C03 (30 mL), water (50 mL) and brine (50 mL), dried over Na2S04, filtered and concentrated to give A-2 (3.10 g, 12.99 mmol) as a solid. 1H NMR (400MHz, CDC13) = 8.54 (d, 1H), 7.85 - 7.60 (m, 2H), 7.25 (d, 1H), 4.63 (d, 2H).
