Versuchsvorschrift

Using the same method as for compound of Example 8 this compound is prepared from 20.4 g (0.06 mol) of 3,5-dibromo-2,6-dimethoxybenzoic acid, 50 ml of thionyl chloride and 7.7 g (0.06 mol) of 2-(aminomethyl)-1-ethylpyrrolidine. The obtained product is recrystallized from ethanol-ethyl ether. Yield: 20.2 g, m.p. 164°-65° C. The free base is precipitated from the water solution of the hydrochloric salt by the addition of sodium hydroxide, m.p. 133°-134° C.
