Reaction Steps

A solution of 4-amino-1,2-diethylpyrazolidine (1.26 g, 8.8 mmol) in anhydrous toluene (5 ml) was added to a solution of 3,5-dichlorophenyl isocyanate (1.71 g, 9.1 mmol) in dry toluene (20 ml) and the mixture stirred overnight. The precipitated solid was collected, washed with toluene and dried to give the title compound, 1.94 g. This was converted to the 1:1 maleate, mp 165°-167° C.
