Reaction Steps
To a suspension of 12 g of 3,5-dibromopyridine and 40 g of 60% NaH in DMF was added 4.05 mL of MeOH, and the reaction mixture was stirred for 4 hours at room temperature and 1 hour at 60° C. The DMF was removed under reduced pressure, and the residue was taken directly to the next step. MS (CI/NH3) m/z 188/190 (M+H)+, 205/207 (M+NH4)+. 1H NMR (CDCl3, 300 MHz) δ: 8.32 (d, J=1.8 Hz, 1H), 8.27 (d, J=2.6 Hz, 1H), 7.42 (dd, J=1.8, 2.6 Hz, 1H), 3.88 (s, 3H).
