Procedure
5.34 g (30.0 mmoles) of 2,5-dichlorophenoxyamine was dissolved in 50 ml of toluene, and then 2.74 g (33.0 mmoles) of allyl isocyanate was added. The mixture was stirred at a temperature of from 25° to 30° C. for 12 hours. The crystals precipitated in the reaction solution were collected by filtration and washed with hexane, whereby, 3.96 g of the desired product was obtained as light yellow crystals (yield: 51%).
