Participants

Reaction Steps

To a stirred solution of tin (II) chloride dihydrate (32.87 grams) in concentrated hydrochloric acid (93 mL) at 50° C. was added 3,5-diacetylnitrobenzene (7.54 grams). The heat was removed immediately and an exotherm occurred. The mixture was stirred for 5 minutes, cooled with an ice bath, and neutralized with saturated potassium carbonate solution. The aqueous phase was extracted with several portions of ethyl acetate, dried over anhydrous sodium sulfate and concentrated in vacuo to afford 3.01 grams of the title compound. 1H NMR δ 7.77 (s, 1), 7.48 (s, 2), 5.16 (br s, 2), 2.55 (s, 6).
