Reaction Steps

A solution of 500 mg (2.73 mmol) 5-bromopicolinonitrile, 63 mg (0.07 mmol) Pd2 dba3 and 130 mg (0.27 mmol) 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl in 20 ml DME was stirred and degassed with N2 for 10 min. 1.45 g (6.83 mmol) K3PO4 and 297 μl (3.0 mmol) piperidine were added. The mixture was heated at 80° C. under N2 over night. The mixture was cooled to r.t. and filtered through a plug of SiO2 with CH2Cl2/MeOH 9:1. The filtrate was concentrated and purified by flash chromatography (SiO2, Pet. ether/EtOAc 4:1→1:1) to afford 323 mg (63%, yellow oil).
