Procedure

N-(4-(4-(4-chlorophenylsulfinyl)-3-cyano-5-(1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl)thiophen-2-yl)pyridin-2-yl)acetamide (0.0315 g, 0.0570 mmol) was dissolved in TFA (5.00 mL, 64.9 mmol). The mixture was stirred at room temperature for 1 hr, and the solvent was evaporated. 10 ml DCM was added to redissolve the material followed by the addition of triethylamine (1 mL). The solvent was evaporated off, and the mixture was purified by silica gel column. The eluent was 0-6% methanol in hexane to yield a solid product (0.0112 g, yield 41.9%) LCMS: (AA) ES+ 469, 471. 1H NMR (300 MHz, MeOD) δ: 8.65 (s, 1H), 8.51 (s, 1H), 8.42 (d, 1H), 8.06 (d, 2H), 7.58 (d, 2H), 7.44 (dd, 1H), 2.25 (s, 3H).
