Procedure
The 4-(2-phthalimidoethylamino)-3,5-dimethyl-1-phenylpyrazole used as starting material is obtained in a manner analogous to that described in Example 1 by reacting N-(2-bromoethyl)-phthalimide with 4-amino-3,5-dimethyl-1-phenylpyrazole. After chromatographic purification on a silica gel column (methylene chloride-ethyl acetate 6:4 v/v), it is obtained in a yield of 56% of theory in the form of a light brownish colored oil.
