実験手順

5.6 g of the product obtained in Stage 1 above is introduced into 8 ml of ammonium hydroxide, the mixture is taken to about -5° C. and 1.58 g of ammonium chloride and 1.23 g of sodium cyanide are added successively and the reaction medium is left to rise to ambient temperature for about 40 minutes then heated at 40° C.±5° C. under agitation overnight. It is returned to ambient temperature and extraction is carried out 3 times with chloroform, the organic phase is washed with salt water and dried. After purification on silica, eluting with cyclohexane-ethyl acetate: 3-7 with 0.5% of triethylamine, 4.41 g of expected product (pale yellow syrup) is obtained.
