Reaction Steps

tert-Butyl 4-(5-(3-(2-methylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)azepane-1-carboxylate (70.4 mg, 0.119 mmol) was dissolved in CH2Cl2 (2 mL) and TFA (2 mL) was added. After 10 minutes the reaction was concentrated and placed on high vacuum pump to remove excess TFA. The residue was dissolved in CH2Cl2 (2 mL) and triethylamine (82.3 μL, 0.591 mmol) and acetic anhydride (16.7 μL, 0.177 mmol) were added. After 10 minutes the reaction was partitioned between saturated aqueous NaHCO3 and EtOAc, dried over sodium sulfate, filtered and concentrated. The residue was purified over silica gel (10% methanol in EtOAc) to afford 1-(4-(5-(3-(2-methylpyridin-3-yloxy)-5-(pyridin-2-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)azepan-1-yl)ethanone dihydrochloride (68.2 mg, 0.112 mmol, 95.2% yield) as a solid after HCl salt formation. Mass spectrum (apci) m/z=534.2 (M+H-2HCl).
