Ethyl Acetate → 1-(2-chloro-5-nitropyridin-4-yl)ethanone

Participants

Reaction Steps

To a solution of 1-(2-chloro-5-nitropyridin-4-yl)ethanol (1.0 equiv.) in dichloromethane (0.1 M) was added Dess-Martin periodinane (1.8 eq.) and the solution was stirred for 16 hours. The solution was poured into ethyl acetate (800 mL), was washed with 1:1 10% Na2S2O3/NaHCO3(sat.) (4×), with NaCl(sat.), dried over MgSO4, filtered and concentrated yielding 1-(2-chloro-5-nitropyridin-4-yl)ethanone (96%) as a yellow solid. LCMS (m/z): 201.0 (MH+); LC Rt=2.80 min. 1H NMR (CDCl3): δ 9.18 (s, 1H), 7.36 (s, 1H), 2.60 (s, 3H).
