Reaction Steps

A mixture of tert-butyl (4-bromo-2-chloro-5-cyanophenyl)(4-methoxybenzyl)carbamate (363 mg, 0.803 mmol), tert-butyl (2-(methylamino)ethyl)carbamate (182 mg, 1.05 mmol), Pd2(dba)3 (51.5 mg, 0.056 mmol), BINAP (105 mg, 0.169 mmol), and Cs2CO3 (524 mg, 1.61 mmol) in a dry microwave vial was flushed with nitrogen. Toluene (5 mL) was added and the vial was sealed and heated at 100° C. overnight. The reaction was diluted with EtOAc and filtered through celite. The solvent was removed from the filtrate and silica gel radial chromatography eluting with hexane containing 5 to 30% EtOAc afforded tert-butyl (4-((2-((tert-butoxycarbonyl)amino)ethyl)(methyl)amino)-2-chloro-5-cyanophenyl)(4-methoxybenzyl)carbamate (397 mg) as an oil.
