106-93-4
32933-03-2
Step 1) Synthesis of ethyl 1-acetylcyclopropanecarboxylate: To a solution of ethyl 3-oxobutanoate (26 g, 200 mmol) in acetone (500 mL) was added potassium carbonate (82.8 g, 600 mmol) followed by 1,2-dibromoethane (45.12 g, 240 mmol). The reaction mixture was refluxed for 24 hours. After completion of the reaction, the mixture was filtered and the filtrate was concentrated under vacuum. The residue was purified by silica gel column chromatography with an eluent ratio of 1:50 (v/v) ethyl acetate/hexane to afford the target compound ethyl 1-acetylcyclopropanecarboxylate as a colorless oil (18.7 g, 60% yield). Mass spectrum (ESI, cation mode) m/z: 157 (M+1); 1H NMR (400 MHz, CDCl3) δ: 1.25-1.29 (t, J=7.2 Hz, 3H), 1.45 (s, 4H), 2.45 (s, 3H), 4.18-4.20 (q, 2H).
