실험 절차

To a solution of potassium tert butoxide (1.0M in THF, 3.20 Kg, 3.55 mol) in tetrahydrofuran (2.1 L) was added diethyl (cyanomethyl)phosphonate (642 g, 3.62 mol), maintaining the temperature below 5° C. The resulting solution was aged for 2 h and a solution of 4-[(4-chlorophenyl)sulfonyl]-4-(2,5-difluorophenyl)cyclohexanone (1.07 Kg, 2.78 mol) (Example 4) in tetrahydrofuran (3.9 L) was added. After the reaction was completed, isopropyl acetate (13.1 L) and water (26.3 L) were added. The organic layer was washed with brine and then concentrated to 1 L. Heptane (10.5 L) was added. The resulting solid was filtered, washed with heptane, dried in vacuo at 37° C. and then slurried in diethyl ether (5 L). Filtration and drying in vacuo afforded 989 g (87% yield) of [4-[(4-chlorophenyl)sulfonyl]-4-(2,5-difluorophenyl)cyclohexylidene]acetonitrile. 1H NMR (CDCl3) 7.41-7.34 (4H, m), 7.25-7.06 (2H, m), 6.94-6.87 (1H, m), 5.12 (1H, s), 3.05-3.03 (1H, m), 2.92-2.86 (2H, m), 2.54-2.50 (1H, m), and 2.30-2.03 (4H, m).
