Reaktionsschritte
Under N2, methyl 2-chloro-6-methylisonicotinate (CAS 3998-90-1) (1.000 g, 5.39 mmol, Eq: 1.00), zinc cyanide (759 mg, 6.47 mmol, Eq: 1.2) and Tetrakis-triphenylphosphin-palladium (623 mg, 539 μmol, Eq: 0.1) were mixed in DMF (17 ml). The RM was stirred under microwave at 160° C. for 30 minutes. Control with TLC: the reaction was finished. The RM was partitioned between EtOAc and water; extracted; the organic phase was dried over MgSO4; filtered; concentrated in vacuo. The crude material was purified by flash chromatography (silica gel, 100 g, 5% to 30% EtOAc in heptane). Purple solid. MS (ISP): 177.2 ([M+H]+)
