Reaction Steps

5 ml. of concentrated sulfuric acid are added dropwise to the suspension of 6 g. of 5-nitrofurfurylidenediacetate in 100 ml. of ethanol, and the mixture is stirred for 10 to 30 minutes at 50°C. Thereafter a solution of 6 g. of 5,6-dimethoxyindazole-3-carboxylic acid hydrazide in 100 ml. of dimethylformamide is added, and the mixture is allowed to stand at room temperature for 24 hours. 6.3 g. (70 %) of 5,6-dimethoxyindazole-3-carboxylic acid-(5'-nitro-furfurylidene)-hydrazide are obtained; m.p.: 334°C. This compound is identical with Compund 26 of Table 5.
