실험 절차

To a stirred slurry of 4-nitro-2-cyanophenyl phenyl sulfide (13.3 g, 5.19 mmol) and 100 mL of absolute ethanol was added stannous chloride dehydrate (58.6 g, 26 mmol) in one portion. The mixture was heated to 60° C. where an exothermic reaction caused the solution to strongly reflux. The mixture was allowed to stir at ambient temperature for 30 min., poured onto ice-water and made strongly basic by the addition of 350 mL of 15% NaOH. The mixture was extracted with methylene chloride (4×275 mL), the extracts dried (MgSO4), filtered, and the solvent removed in vacuo to yield an oil which was chromatographed on 300 g of silica gel using a methylene chloride (20%, 40%, 60% 80% and 100%) in hexane gradient. The proper fractions were combined and the solvent removed to yield the 4-amino-2-cyanophenyl phenyl sulfide (10.62 g, 91%) as a pale yellow solid; mp 73°-75° C. 1H--NMR (300 MHz, CDCl3): 4.01 (s, 2H, NH2), 6.78 (dd 1H, J=8.5, 2.6, aromatic), 6.95 (d, 1H, J=2.6, aromatic), 7.18-7.29 (m, 5H, aromatic), 7.34 (d, 1H, J=8.5, aromatic). MS (CI, CH4): 227(M+1).
