Reaction Steps

To a stirred solution of ethyl 4-oxocyclohexane carboxylate (5 g, 29.41 mmol) and ethane-1,2-dithiol (4.14 g, 44.11 mmol) in DCM (25 mL) was added BF3.Et2O (4.17 g, 29.41 mmol) at 0° C. and the reaction mixture was allowed to stir at 20-35° C. for 2 h. Then the reaction mixture was rotary evaporated under vacuum to get residue which was purified by column chromatography using mixture of 5% ethyl acetate/hexane as an eluent to get the desired compound as a yellow liquid (5.4 g, 75%); 1H NMR (400 MHz, DMSO-d6) δ 4.05 (q, J=7.4 Hz, 2H), 3.34-3.26 (m, 4H), 2.42-2.34 (m, 1H), 2.10-2.02 (m, 2H), 1.96-1.84 (m, 4H), 1.66-1.54 (m, 2H), 1.17 (t, J=7.3 Hz, 3H).
