3,5-Dichloroaniline → HCID 68540128, compound

Participants

Reaction Steps

19.2 g of tricyclo-[3.2.2.02.4 ]-nonane-6,7-dicarboxylic acid anhydride (prepared from the cycloheptatriene/maleic acid anhydride adduct (see Ex. 1a) by catalytic hydrogenation, K. Alder, Ber. 86, 1528-39 (1953) and 19.4 g of 3,5-dichloroaniline are refluxed in 1000 ml of toluene for 16 hours, whereby thewater forming during the reaction is separated with a water separator. After cooling, the toluene is removed in vacuum, and the residue recrystallised from ethyl acetate, M.P. 145° - 153° C.
