Three hundred milliliters of a toluene solution of a mixture of N-isopropyl-1,2-ethylenediamine (20.0 g), 3-chloro-2',6'-dimethylpropionanilide (13.9 g) and triethylamine (10 ml) is treated as in Example 1 to provide a pale yellow powder. Recrystallization from n-hexane provides a colorless needle in an amount of 11.5 g (yield: 63.2%). m.p. 69.5° C.
