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

実験手順: To a solution of 4-fluoro-3-methoxyphenylacetonitrile (10.8 g, 65.4 mmol) in 200 ml EtOH was added a sodium ethoxide 21% solution in EtOH (26.9 ml, 71.9 mmol). Benzaldehyde was added (6.64 ml, 65.4 mmol) and stirred at room temperature over night. The white precipitate was filtered and washed with diethylether and dried to obtain 14.23 g of pale yellow crystals (86%). The white precipitate was filtered washed with diethylether dried

実験手順: 16.67 g (100.93 mmol) of (4-fluoro-3-methoxyphenyl)-acetonitrile is introduced with 30.1 g (211.96 mmol) of methyliodide into 158 ml of dimethylformamide. At 0° C., 8.50 g (211.96 mmol) of a 55-60% sodium hydride suspension is added in portions. After stirring overnight at room temperature, the reaction mixture is poured into ice water and then extracted three times with methyl tert-butyl ether. The combined organic extracts are washed with water and with brine. After the solvent is dried and spun off, the residue is chromatographed on silica gel (mobile solvent ethyl acetate/hexane). 5.11 g (26.2%) of the desired compound and 6.18 g of the monomethyl compound, which is realkylated, are isolated. extracted three times with methyl tert-butyl ether The combined organic extracts are washed with water and with brine After the solvent is dried the residue is chromatographed on silica gel (mobile solvent ethyl acetate/hexane) are isolated
