Methyl iodide → HCID 66977074, compound

Participants

Reaction Steps

To an ice-cold solution of ethyl 1-(5-bromopyrimidin-2-yl)piperidine-2-carboxylate (0.37 g, 1.18 mmol) in THF (25 mL) was added NaH (60% dispersion in mineral oil, 0.06 g, 1.41 mmol) portion wise. The mixture was stirred at the same temperature for 45 min followed by addition of MeI (0.52 mL, 8.26 mmol) at 0° C. The temperature of the reaction was slowly raised up to rt and left to stir for 16 h. The reaction was then cooled to 0° C., quenched by drop wise addition of ice-cold water then extracted with EtOAc (3×100 mL). The combined organics were washed with brine, dried (Na2SO4), filtered and concentrated under reduced pressure. The crude residue was purified over 100-200 M silica-gel by using 2% EtOAc: hexane to obtain the desired product as off-white solid (0.115 g, 32% yield). MS: 300.09 [M+H]+.
