Reaction Steps
A solution of t-butyl piperazine-1-carboxylate (1.96 g, 10.54 mmol, 2.00 equiv), 1-bromo-3-chlorobenzene (1 g, 5.26 mmol, 1.00 equiv), BINAP (330 mg, 0.53 mmol, 0.10 equiv), Pd2(dba)3 (243.8 mg, 0.27 mmol, 0.05 equiv), NaOt-Bu (1.59 g, 16.56 mmol, 3.00 equiv), and toluene (17 mL) was placed in a 100-mL round bottom flask, stirred overnight at 100° C. in an oil bath, and concentrated under vacuum. Purification via silica gel column (PE/EA (50:1)) yielded 1.3 g (83%) of t-butyl 4-(3-chlorophenyl)piperazine-1-carboxylate as a yellow solid.
