反応条件: temp:0.00; pressure:0.00; stir:

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

実験手順: A suspension of 4-bromobenzoylacetonitrile (500 mg) in ethanol (5 mL) and acetic acid (300 μL) was heated with sodium cyanoborohydride (280 mg) using an 80° C. hot plate for 2 hours. After cooling to ambient temperature, the mixture was diluted with water and concentrated to a syrup, which was diluted with ethyl acetate and washed with water, sat. NaHCO3, and brine. The extract was dried with mgSO4, filtered, and evaporated to provide 510 mg of a cloudy oil, which was filtered through silica gel using 1:1 ethyl acetate/hexane to provide the product (496 mg) as a thick oil. using an 80° C. for 2 hours concentrated to a syrup, which was diluted with ethyl acetate washed with water, sat. NaHCO3, and brine The extract was dried with mgSO4 filtered evaporated to provide 510 mg of a cloudy oil, which was filtered through silica gel using 1:1 ethyl acetate/hexane

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

実験手順: A solution containing 9.4 g of KCN in 20 ml of water is prepared and then it is poured dropwise over a mixture containing 20 g of 2-bromo-1-(4-bromo-phenyl)ethanone dissolved in 800 ml of 90% ethanol. After stirring for 5 hours at RT, the solid formed is filtered and then it is rinsed with ice-cold water. The solid obtained is dissolved in 400 ml of water and then activated charcoal is added, the mixture is kept stirring for 20 minutes, and then filtered on Celite®. The filtrate obtained is treated with HCl at 10% and the white precipitate formed is filtered, washed with water and then dried under vacuum. 7.63 g of the expected compound are obtained. m.p.=164° C. is prepared it is poured dropwise over a mixture the solid formed is filtered it is rinsed with ice-cold water The solid obtained the mixture is kept stirring for 20 minutes filtered on Celite® The filtrate obtained the white precipitate formed is filtered washed with water dried under vacuum
