Reaction Steps

A mixture of 1-[1-(2-methoxy-ethoxymethyl)-5-piperidin-1-yl-6-trifluoromethoxy-1H-benzoimidazol-2-yl]-1H-pyrazole-4-carboxylic acid ethyl ester (0.300 g, 0.586 mmol), glacial acetic acid (5.9 mL), and 6M aqueous HCl (6.9 mL) was heated at 100° C. for 4.5 h in a sealed tube. The reaction mixture was cooled to 23° C. and then 0° C. The resulting precipitate was filtered and washed with cold water to yield the titled compound (60.0 mg, 26%). MS (ESI/CI): mass calcd. for C17H16F3N6O3, 395.1; m/z found, 396.1 [M+H]+. 1H NMR (400 MHz, DMSO-d6): 8.84 (d, J=0.6 Hz, 1H), 8.27 (d, J=0.6 Hz, 1H), 7.47 (br s, 1H), 7.21 (br s, 1H), 2.98-2.89 (m, 4H), 1.71-1.59 (m, 4H), 1.58-1.47 (m, 2H).
