Reaction Steps
To a solution of 5-(6-chloro-pyridin-3-yl)-5-cyano-2-hydroxy-cyclohex-1-enecarboxylic acid methyl ester (4.2 g, 14 mmol) in DMSO (15 mL) was added sodium chloride (090 g, 16 mmol) and water (0.77 mL). The reaction mixture was heated at 160° C. for 6 hours. The reaction mixture was then cooled to room temperature and poured into water (50 mL). The aqueous layer was extracted with diethyl ether (3×250 mL). The combined organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue obtained was purified by column chromatography on silica gel to afford 1-(6-chloro-pyridin-3-yl)-4-oxo-cyclohexanecarbonitrile (1.7 g, 52%). 1H NMR (400 MHz, CDCl3) δ ppm 8.59 (s, 1 H), 7.83 (dd, J=8.4, 2.2 Hz, 1 H), 7.44 (d, J=8.5 Hz, 1 H), 2.89-2.98 (m, 2 H), 2.60-2.66 (m, 2 H), 2.48-2.54 (m, 2 H), 2.25-2.33 (m, 2 H).
