The downstream synthesis method of this compound is introduced below.
A suspension of tert-butyl 4-(((trifluoromethylsulfonyl)oxy)piperidine-1-carboxylate (6.2 g, 21.1 mmol), 2-chloropyrimidin-5-ol (2.5 g, 19.2 mmol) and potassium carbonate ( 13.3 g, 96 mmol) in dimethylsulfoxide (100 mL) was stirred at llOoC for 16 hours. The reaction mixture was cooled to room temperature and dimethylsulfoxide was distilled off under reduced pressure. The residue was then treated with water (50 mL) and precipitate was formed, filtered off and purified by column chromatography eluting with hexanes: ethyl acetate mixture (3:2) by volume to afford the title compound (2.0 g, 31.7 %) as a white crystalline powder:
