실험 절차

Anisole (1 ml) was added to a solution of an about 1:1 mixture (4.4 g) of ethyl 1-(4-methoxybenzyl)-4-(4,5-dimethoxy-2-nitrobenzoyl)-1H-1,2,3-triazole-5-carboxylate (Synthesis Example 1, b-1) and ethyl 1-(4-methoxybenzyl)-5-(4,5-dimethoxy-2-nitrobenzoyl)-1H-1,2,3-triazole-4-carboxylate(Synthesis Example 1, b-2) in trifluoroacetic acid (10 ml), and the mixture was stirred at 60° C. for 10 hr. After the mixture was allowed to stand for cooling, the solvent was evaporated under reduced pressure, followed by azeotropic evaporation using toluene. The resultant crystal was collected by filtration, washed with diethyl ether, and then dried to give ethyl 5-(4,5-dimethoxy-2-nitrobenzoyl)-1H-1,2,3-triazole-4-carboxylate (3.12 g, 95%).
