2-(4-iodophenoxy)acetonitrile

反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a stirred solution of 4-iodo phenol (700 mg, 3.1 mmol) in acetonitrile (7 ml) was added K2CO3 (1.31 g, 9.5 mmol), followed by bromo acetonitrile (410 mg, 3.4 mmol) at 20-35° C. and the reaction mixture was stirred at 80° C. for 6 h. The progress of the reaction was monitored by TLC. After 6 h of stirring, the mixture was cooled to 20-35° C., diluted with water (50 ml) and extracted with ethyl acetate (2×50 ml). The combined organic layers were washed with brine (50 ml), followed by drying over anhydrous Na2SO4 and filtering. The filtrate was rotary evaporated to get residue which was purified by column chromatography using a mixture of 15% ethyl acetate/hexane as an eluent to get the desired compound as a pale yellow liquid (400 mg, 51%). 1H NMR (400 MHz, DMSO-d6) δ 7.65 (dt, J=5.4, 2.9 Hz, 2H), 6.79-6.77 (m, 2H), 4.74 (s, 2H). After 6 h of stirring the mixture was cooled to 20-35° C. extracted with ethyl acetate (2×50 ml) The combined organic layers were washed with brine (50 ml) by drying over anhydrous Na2SO4 filtering The filtrate was rotary evaporated to get residue which was purified by column chromatography a mixture of 15% ethyl acetate/hexane as an eluent
