Reaction Steps

To a solution of ethyl-2-mercaptoacetate (0.7 mmol) in dry DMF (2.5 ml), sodium hydride (0.85 mmol) was added 0° C. After 15 minutes, 4-fluoro-3-nitrobenzaldehyde (0.7 mmol) was added and the mixture was heated at 60° C. overnight and monitored by TLC until completion. After cooling, the solvent was removed under reduced pressure. The residue was chromatogaphed on a silica gel column (cyclogexane/ethyl acetate 4/1 as eluent) to give 46 mg of ethyl 2-(4-formyl-2-nitrophenylthio)acetate as yellow compound (yield 24%). 1H NMR, (250 MHz, CDCl3): δ 1.25 (t, J=7.5 Hz, 3H), 3.80 (s, 2H), 4.21 (q, J=7.75, 2H), 7.64 (d, J=9.75, 1H), 8.03 (d, J=9.75, 1H), 8.68 (s, 1H), 10.00 (s, 1H) 13C NMR (126 MHz, CDCl3): δ 15.4, 36.5, 63.8, 128.5, 129.3, 133.9, 145.6, 147.1, 169.5, 190.1.
