Combine 2-chloro-5-fluoro-4-[7-(2-fluoro-5-methyl-pyridin-4-yl)-benzo[b]thiophen-2-yl]-pyrimidine (200 mg, 0.54 mmol) and 2-[1,2,3]triazol-1-yl-ethylamine (120 mg, 21.1 mmol) in n-butanol (2 mL), alternative dioxane, dioxane-NMP (N-methylpyrrolidinone), NMP alone as solvent] in a pressure vessel. Heat the mixture in an oil bath at 120-150° C. overnight (or in microwave reactor for 10-60 min). Dilute the mixture with chloroform/IPA (3/1). Wash the solution with saturated aqueous sodium chloride, dry over sodium sulfate, and concentrate the solution in vacuo to a dark residue. Purify by column chromatography (DCM→10% methanol in DCM) to afford the title compound as a yellow solid (140 mg, 59%). MS (ES) m/z 450 [M+1]+.
