Reaction Steps

A mixture of 3-{3-[5-Chloro-3-(4-chloro-3-trifluoromethyl-benzenesulfonylamino)-pyridin-2-yl]-[1,2,4]triazol-4-yl}-butyric acid ethyl ester (27 mg, 0.05 mmol), lithium borohydride (2.0M, 0.14 ml, 0.28 mmol), 1.5 ml of THF and 0.02 ml of methanol was stirred at room temperature for 2 hours. The mixture was mixed with diluted HCl (1.0M), extracted with ethyl acetate, and the extracts were combined and washed with brine and dried. After concentration the residue was purified by prep TLC to afford title compound as a white solid. 1H NMR: (DMSO-d6, ppm): 9.03 (s, 1H), 8.30 (m, 1H), 8.11 (m, 1H), 8.02 (m, 1H), 7.91 (m, 1H), 7.83 (m, 1H), 3.28 (m, 1H), 3.19 (m, 2H), 1.91 (m, 2H), 1.42 (d, 3H). MS (ES) [M+H]+ expected 510.0, found 510.0.
