3-(8-azabicyclo[3.2.1]octan-3-yl)-N-(3-(2-methylpyridin-3-yloxy)-5-(trifluoromethyl)pyridin-2-yl)-1,2,4-thiadiazol-5-amine (45 mg, 0.0973 mmol) was dissolved in CH2Cl2 (2 mL) and triethylamine (67.8 μL, 0.486 mmol) and acetic anhydride (13.8 μL, 0.146 mmol) were added. After 10 minutes the reaction was partitioned between saturated aqueous NaHCO3 and CH2Cl2, dried over sodium sulfate, filtered and concentrated. The residue was purified on silica gel (10% methanol in EtOAc) to afford 1-(3-(5-(3-(2-methylpyridin-3-yloxy)-5-(trifluoromethyl)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)-8-azabicyclo[3.2.1]octan-8-yl)ethanone hydrochloride (25 mg, 0.0462 mmol, 47.5% yield) as a solid after HCl salt formation. Mass spectrum (apci) m/z=505.2 (M+H—HCl).
