Reaction Steps

A mixture of (R)-tert-butyl 3-methylpiperazine-1-carboxylate (0.072 g, 0.36 mmol), 1-(benzyloxy)-4-bromobenzene (0.079 g, 0.3 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (0.035 g, 0.06 mmol), tris(dibenzylideneacetone)dipalladium(0) (0.027 g, 0.03 mmol) and sodium 2-methylpropan-2-olate (0.101 g, 1.05 mmol) in toluene (2 mL) was flushed with nitrogen and sealed into a microwave tube. The reaction was heated to 150 °C for 10 minutes in the microwave reactor and cooled to RT. Only a small amount of the desired product was visible by LCMS. The reaction was not progressed further.
