Procedure

A solution of 2.67 g of 3,4-dichloroaniline in 10 ml of toluene was added to 3.87 g of 2,3-dihydro-5-indenylsulfonylisocyanate in 20 ml of toluene. After stirring 7 hours, the resulting precipitate was recovered by filtration, washed with toluene and dried providing 5.38 g of the title product, m.p. 155.5°-158° C.
