Procedure

(g) 2-(4-(1-(4-Fluorophenyl)-1H-indazol-5-yl)tetrahydro-2H-pyran-4-yl)-2-methylpropanoic acid (50 mg, 0.13 mmol) was dissolved in 5 mL DCM, 32 uL pyridine, and treated with 27 uL cyanuric fluoride. After 1 h, the reaction was extracted from NaHCO3 with EtOAc×3. The combined organic layers were dried over MgSO4, filtered, concentrated and taken up in 2 mL NMP and treated with triethylamine (100 uL) and NH4Cl (50 mg). The reaction was purified by HPLC to give 23 mg of 2-(4-(1-(4-fluorophenyl)-1H-indazol-5-yl)tetrahydro-2H-pyran-4-yl)-2-methylpropanamide. (M+H)+=382.
