Procedure
The title compound was prepared according to the procedure described for Example 2 using carbonyldiimidazole (1.2 g, 7.4 mmol), 2,4-thiophene-dicarboxylic acid (0.5 g, 3.0 mmol), and piperonylamine (1.05 g, 6.7 mmol) to afford 1.2 g of thiophene-2,4-dicarboxylic acid bis-[(1,3-benzodioxol-5-ylmethyl)-amide]. Recrystallization of a sample from ethanol gave product with a mp 174-175° C.
