Reaction Steps

Combine 2-chloro-5-fluoro-4-(7-{2-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-phenyl}-benzo[b]thiophen-2-yl)-pyrimidine (250 mg, 0.52 mmol) and 2-[1,2,3]triazol-1-yl-ethylamine (140 mg, 1.29 mmol) in tert-butanol (2.6 mL, alternative dioxane, n-butanol, dioxane-NMP, NMP alone as solvent) and NMP (1.3 mL) in a pressure vessel. Heat the mixture in an oil bath at 120-150° C. overnight (or in microwave reactor for a certain period of time). Dilute the mixture with chloroform/IPA (3/1). Wash the solution with aqueous saturated sodium chloride. Dry over sodium sulfate. Concentrate the solution in vacuo. Purify by column chromatography (DCM to 10% methanol in DCM) to give the title compound as a yellow solid (160 mg, 65%). MS (ES) m/z 477 [M+1]+.
