After stirring for 30 minutes, the reaction mixture was neutralised with Na2CO3. A diazonium salt obtained by reaction of KCN (2.4 eq., 48 g), water (120 ml) and CuCN (1.12 eq., 31 g) was added dropwise to the reaction mixture within 30 min and the mixture was stirred for a further 30 min at 75 0C. After complete reaction, the reaction mixture was extracted with EE (3 x 500 ml), the combined organic phases were dried over sodium sulphate and the solvent was removed under vacuum. The purification (SiO2, 20 % EE\/hexane) of the residue by column chromatography produced a white solid (J-IV) (6.5 g, 15.1 % yield).<\/p>\n<p>These compound has a wide range of applications.
