実験手順

A solution of ethyl 6-[(dimethylamino)methylene]-1,4,4-trimethyl-7-oxo-4,5,6,7-tetrahydro-1H-indazole-3-carboxylate (0.50 g, 1.6 mmol) and N-[3-chloro-4-(4-methyl-piperazin-1-yl)-phenyl]-guanidine (0.48 g, 1.8 mmol) in anhydrous dimethylformamide was heated to 100° C. and kept at this temperature for 37 hours. After cooling, the mixture was diluted with water (50 mL) and the resulting precipitate was collected by filtration and dried to give the title compound (0.72 g, 85% yield) as a yellow solid.
