実験手順
Likewise, ethyl 1-(4-methoxybenzyl)-5-(4,5-dimethoxy-2-nitrobenzoyl)-1H-1,2,3-triazole-4-carboxylate (b-2) (3.12 g, 6.63 mmol) prepared in step (b) was hydrolyzed in a tetrahydrofuran (100 ml) solution with a 1 N aqueous sodium hydroxide solution (13 ml) at room temperature for 3.5 hr. Thus, 1-(4-methoxybenzyl)-5-(4,5-dimethoxy-2-nitrobenzoyl)-1H-1,2,3-triazole-4-carboxylic acid (c-2′: MP) (2.32 g, 79%) was obtained as a yellow crystal powder.
