Reaction Steps

tert-Butyl {2-[(3-bromobenzyl)amino]-2-oxoethyl}carbamate (274 mg), 4-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]morpholine (222 mg), sodium carbonate (81 mg), tetrakis(triphenylphosphine)palladium (88 mg), DME (5 ml), and water (2.5 ml) were put into a 50-ml recovery flask, followed by stirring at 80° C. for 10 hours under a nitrogen atmosphere. The reaction mixture was cooled to room temperature and concentrated under reduced pressure. The obtained residue was subjected to liquid separation with CHCl3 and water. The organic layer was separated, and then the aqueous layer was extracted with CHCl3 again. These organic layers were combined, dried over Na2SO4, and then concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (2% MeOH/CHCl3) to obtain tert-butyl (2-{methyl[(4′-morpholin-4-ylbiphenyl-3-yl)methyl]amino}-2-oxoethyl)carbamate (270 mg) as a pale yellow oil.
