実験手順

Into a 250-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 2-bromo-1-(3-nitrophenyl)ethanone (10.0 g, 41.15 mmol, 1.00 equiv) in THF (150 mL), (2,4-dichlorophenyl)methanamine (7.16 g, 40.91 mmol, 1.00 equiv) and triethylamine (5.96 g, 59.01 mmol, 1.50 equiv). The resulting solution was stirred for 2 h at 25° C. The solids were filtered out. The filtrate was concentrated to dryness and used for next step, assuming theoretical yield.
