[00201] Step 1 : 5-Chloro-2-iodopyrimidine (4 g, 16.64 mmol) and tetrakis(triphenylphosphine)palladium(0) (1.92 g, 1.66 mmol) were suspended in THF (83 mL). 3-Ethoxy-3-oxopropylzinc bromide (33.3 mL, 16.64 mmol) was added, and the resultant mixture was stirred at room temperature for 18 hours. The mixture was diluted with saturated ammonium chloride and water (1 : 1) and extracted with EtOAc (3×100 mL). The combined organic layers were washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by column chromatography on silica gel (EtOAc:Hexanes) to give ethyl 3-(5-chloropyrimidin-2-yl)propanoate. MS ESI calcd for C9H12C1N202 [M + H]+ 215, found 215. ‘H NMR (500 MHz, DMSO-d6) delta 8.82 (s, 2H), 4.00 (q, J= 7.1 Hz, 2H), 3.13 (t, J = 6.9 Hz, 2H), 2.78 (t, J= 6.9 Hz, 2H), 1.1 1 (t, J = 7.1 Hz, 3H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,874676-81-0, its application will become more common.
