Reaction Steps
By a method analogous to that described in Example 1 3-acetamido-1-(3-trifluoromethylphenyl)-2-pyrazoline was reduced with lithium aluminium hydride, using tetrahydrofuran in place of diethyl ether. The hydrochloride of the resulting 3-ethylamino-1-(3-trifluoromethylphenyl)-2-pyrazoline was recrystallized from isopropanol and diethylether, m.p. 171.5°.
