実験手順
3.0 g (7.22 mmol) of aldehyde from Example V dissolved in 30 ml of ethanol are added to a solution of 0.581 g (14.4 mmol) of sodium cyanide and 3.63 g (36.1 mmol) of ammonium carbonate in 30 ml of water and the mixture is stirred for 24 hours at 60° C. Ethanol is then distilled off from the reaction solution, it is diluted with water, acidified to pH 2 with 1N hydrochloric acid with ice-cooling and extracted twice with ethyl acetate. After drying and distilling off the solvent, the crude product (4.03 g) is chromatographed on silica gel 60 using methylene chloride with addition of a little methanol in the ratio 20:1 to 20:2.5.
