Reaction Steps

In a 5 ml MW vial, Pd2((dba)3 (7.23 mg, 7.90 µmol), 2,2'-bis(diphenylphosphanyl)-1,1'-binaphthalene (BINAP) (9.71 mg, 0.02 mmol), sodium 2-methylpropan-2-olate (174 mg, 1.81 mmol), (R)-3-aminopiperidin-2-one (119 mg, 1.04 mmol) and 2-bromo-3-chloropyridine (200 mg, 1.04 mmol) mixed in toluene (2 mL) to give a brown suspension. The mixture was degassed with N2 bubbling for 5 min, then the vial was capped and the reaction stirred at 115°C in an oil-bath over night. The reaction was cooled to rt, DCM and aq NaHCO3 were added, the mixture stirred, filtered through a phase separator and evaporated. LC-MS crude: Traces of product, mainly starting bromide left. Reaction discarded.
