Versuchsvorschrift
A mixture of 2.17 g of ethyl 4-chloro-3-ethyl-1-methylpyrazole-5-carboxylate and 3.24 g of 5-aminomethyl-2-n-butylpyridine was heated at 200° C. for 4 hours under stirring. After cooling to room temperature, the reaction mixture was purified by silica gel columnchromatography to obtain 2.06 g of the compound (NO. 15) listed in Table 1.
