Reaction Steps

(S)-[1-[3-(3-Chloro-phenyl)-[1,2,4]oxadiazol-5-yl]-2-(4-cyclopropyl-5-pyridin-4-yl-4H-[1,2,4]triazol-3-yl)-ethyl]-carbamic acid tert-butyl ester (135 mg) was mixed with 96% formic acid (1.3 mL) and heated at 50° C. for 1 h. The reaction mixture was concentrated in vacuo. The residue was quenched with saturated sodium bicarbonate and extracted with ethyl acetate. The organic layer was dried with sodium sulfate and concentrated. Purification was performed by flash column silica gel chromatography with 2-3% (2 M ammonia methanol) in dichloromethane to give 106 mg of the title compound as an off-white solid. 1H NMR (CDCl3): d ppm 8.73 (d, 2H), 8.03 (s, 1H), 7.93 (d, 1H), 7.69 (d, 2H), 7.46 (d, 1H), 7.42 (t, 1H), 5.02 (dd, 1H), 3.61 (dd, 1H), 3.49 (dd, 1H), 3.35 (m, 1H), 2.47 (br s, 2H), 1.20 (m, 2H), 0.75 (m, 2H)
