2,4-Dichloropyrimidine → HCID 75539526, compound

Participants

Reaction Steps

To a solution of 2,4-dichloropyrimidine (Alfa Aesar, 10 g, 65.8 mmol) and TEA (Sigma-Aldrich, 9.15 mL, 65.8 mmol) in EtOH (68.5 mL) at 0° C. was added ethyl piperidine-3-carboxylate (Sigma-Aldrich, 10.64 mL, 65.8 mmol) in EtOH (13.70 mL). The reaction was then allowed to warm to room temperature while stirring. After 1 hour, the reaction was concentrated and the residue was purified by chromatography through a 340 g silica gel column, eluting with 10% to 80% EtOAc/hexanes, to provide ethyl 1-(2-chloropyrimidin-4-yl)piperidine-3-carboxylate as a colorless oil in 80% yield. 1H NMR (300 MHz, CDCl3) δ ppm 0.94 (t, J=6.94 Hz, 3H) 1.26 (d, J=9.35 Hz, 1H) 1.38-1.62 (m, 2H) 1.66-1.85 (m, 1H) 2.26 (m, 1H) 2.90-3.20 (m, 2H) 3.64 (m, 1H) 3.69-4.09 (m, 3H) 6.23 (d, J=5.85 Hz, 1H) 7.68 (d, J=5.99 Hz, 1H); ESI-MS M+H 270.0.
