Versuchsvorschrift
15.1 g of 4-[4-(2-pyrrolylcarbonyl)-1-piperazinyl]-3-trifluoromethylbenzoylguanidine is taken up in 151 mL of methanol and the resulting suspension is cooled to about 10° C. 16 mL of a saturated ethereal HCl solution are added to this suspension which is thus acidified to a pH of between 1 and 2. Stirring is continued, while cooling with ice, until crystallization is complete. The crystals are suction filtered, washed with cold methanol, and then with cold diethyl ether. Yield: 16.19 g; melting point: 223° C. (uncorrected).
