Procedure

The 2,4-diamino-1-n-heptylbenzene so obtained was used directly for the reaction with acetylene dicarboxylic acid dimethyl ester. The said 1-n-heptyl-2,4-dinitrobenzene was obtained by nitration of n-heptylbenzene in a similar manner to that described for the nitration of n-pentylbenzene in Example 7.
