Reaction Steps

2,4-Dibromo-6-ethyl-pyridin-3-ylamine (105 mg, 0.38 mmoles) was combined with 80% sodium thioethoxide (50 mg, 0.48 mmoles) in anhydrous DMF (2 mL) and was stirred at 50° C. under nitrogen for 2 hours. After this period the reaction mix was combined with water (20 mL) and was extracted with EtOAc (3×20 mL). The combined EtOAc layer was washed with water (3×15 mL) and brine. After drying over anhydrous Na2SO4 the organic layer was evaporated in vacuo to yield crude product. The crude product was purified using flash silica chromatography (0-15% EtOAc/Hexane) to yield 4-bromo-6-ethyl-2-ethylsulfanyl-pyridin-3-ylamine (83 mg, 84%) as a clear residue. 1H-NMR (CDCl3): δ 6.94 (s, 1H), 4.34 (br s, 2H), 2.95 (q, J=7.3 Hz, 2H), 2.68 (q, J=7.6 Hz, 2H), 1.33 (t, J=7.3 Hz, 3H), 1.24 (t, J=7.6 Hz, 3H).
