Following the general procedure of EXAMPLE 149 and making non-critical variations, but using pyrrole-2-carboxylic acid (823 mg, 7.40 mmol) and 4-[N-ethyl-N-(3-ethylamino-2-pyridinyl)aminomethyl]piperidine (970 mg, 3.70 mmol), a crude product is obtained. Chromatography [with 40-100% ethyl acetate/hexane], followed by crystallization from ether/hexane gives the title compound, mp=109°-110°.
