Electric Literature of 6693-08-9 ,Some common heterocyclic compound, 6693-08-9, molecular formula is C4Cl3FN2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
A suspension of 2, 4, 6-trichloro-5-fluoropyrimidine (2.21 g, 8.78 mmol) , (+/-) -trans-methyl 3-aminobicyclo [2.2.2] octane-2-carboxylate (1.75 g, 8.78 mmol) , K2CO3(2.43 g, 17.60 mmol) in DMF (5 mL) was stirred at rt overnight. The reaction was quenched with water (100 mL) , and the resulting mixture was extracted with ethyl acetate (50 mL × 3) . The combined organic layers were washed with saturated brine (50 mL × 3) , dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated in vacuo and the residue was purified by silica gel column chromatography (PE/EtOAc (v/v) = 5/1) to give the title compound as a white solid (2.71 g, 89 %) .MS (ESI, pos. ion) m/z: 348.0 [M+H]+.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 6693-08-9, 2,4,6-Trichloro-5-fluoropyrimidine, other downstream synthetic routes, hurry up and to see.
