Reaction Conditions

Temperature60 °C

Reaction Steps

1.2 eq. of NaCN are suspended in 20 ml of dimethyl sulphoxide. The mixture is heated at 60° C. for 30 minutes and then 1 eq. of the compound obtained in Step C is added gradually. The reaction mixture is stirred for 1 hour at 60° C. and is then hydrolysed. Extraction with ethyl acetate is carried out and the organic phase is washed with water, dried over MgSO4 and evaporated under reduced pressure. The residue obtained is purified by chromatography on silica gel.
