To a stirred solution of phenethyl)pyrazine (0.042 g, 0.121 mmol) and Pd(dppf)2Cl2 (0.0089 g, 0.012 mmol) in toluene (1 mL) was added dimethyl zinc (0.24 mL, 2 M solution in toluene, 0.48 mmol) and the reaction mixture was heated at 80 °C for 27 hrs before a further portion of Pd(dppf)2Cl2 (0.0089 g, 0.0121 mmol) was added and the reaction was stirred at 80 °C a further 24 hrs. The mixture was cooled and water (2 mL) added. Ethyl acetate (5 mL) was added and the organic layer extracted. The aqueous layer was washed with further ethyl acetate (2 x 5 mL). The organic layers were combined, dried over magnesium sulfate, filtered and concentrated. The crude material was purified by flash column chromatography (0-5% ethyl acetate in cyclohexane)
