실험 절차

To a mixture of 1-[4-chloro-1-(2-methoxy-ethoxymethyl)-1H-benzoimidazol-2-yl]-1H-pyrazole-4-carboxylic acid ethyl ester (0.370 g, 0.980 mmol) and EtOH (2.5 mL), was added 4M HCl in dioxane (2.5 mL, 10 mmol). The mixture was stirred for 18 h at 23° C. The resulting white precipitate was filtered and washed with EtOH to yield the titled compound (0.260 g, 93%). MS (ESI/CI): mass calcd. for C13H11ClN4O2, 290.1; m/z found, 291.1 [M+H]+. 1H NMR (500 MHz, DMSO-d6): 13.83 (s, 1H), 8.98 (s, 1H), 8.45-8.29 (m, 1H), 7.46 (s, 1H), 7.38-7.16 (m, 2H), 4.59-4.01 (m, 2H), 1.60-1.01 (m, 3H).
