Participants

Reaction Steps

m.p. 151°-152° C., 24.9 g., was prepared as in Example 1 using 3,4-methylenedioxybenzoyl chloride (prepared as in Example 6 using 30 g. of 3,4 -methylenedioxybenzoic acid) in 150 ml. of ethylene dichloride, 10.5 g. of 1,7-heptanediamine, 200 ml. of 10% aqueous potassium hydroxide solution, 500 ml. of ethylene dichloride and recrystallization from ethanol using decolorizing charcoal.
