実験手順
2,6-dichlorophenylisocyanate (1.54 g, 8.18 mmol) was added under nitrogen to a solution of N-(2,6-dibromo-4-nitrobenzyl)-N-(-4-methoxybenzyl)amine (3.35 g, 7.79 mmol) in CH2Cl2 (95 mL). The resulting mixture was stirred at rt for ca. 3 h. The reaction mixture was then concentrated under reduced pressure to yield N-(2,6-dibromo-4-nitrobenzyl)-N′-(2,6-dichlorophenyl)-N-(4-methoxybenzyl)urea as a yellow solid. Mass spectrum (ESI) 616 (M+1).
