Synthesis Example 25
N-[1-((2-chloropyrimidin-5-yl)methyl)pyridin-2(1H)-ylidene]-2,2,2-trifluoroacetamide (Compound 243)
2-chloro-5-methylpyrimidine (1.04 g, 8.13 mmol) was dissolved in 30 mL of carbon tetrachloride, 1.73 g (9.75 mmol) of N-bromosuccinimide and 20 mg of benzoyl peroxide were added, and the mixture was refluxed under heating for 6 hours.
Following reaction completion, the reaction mixture was returned to room temperature, concentrated under reduced pressure, and purified by silica gel column chromatography (hexane/ethyl acetate=3:1), affording 641 mg of 5-bromomethyl-2-chloropyridine (yield, 38%).
1H-NMR (CDCl3, δ, ppm): 4.42 (2H, s), 8.66 (2H, s)
