Electric Literature of 1805-32-9 ,Some common heterocyclic compound, 1805-32-9, molecular formula is C7H6Cl2O, 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.
General procedure: Dissolved e1 – e3 (1.0 equiv) completely in dry DMF, then added NaH (2.2 equiv) to the reaction slowly at 0 C and the resulting mixture was stirred for 20 minutes, and then corresponding R2(CH2)nOH or g1 – g5 (1.2 equiv) was added and the reaction mixture was stirred for 1 h at room temperature. Then it was quenched by H2O, washed with brine and extracted with ethyl acetate. The combined organic layers were dried over anhydrous Na2SO4 and concentrated under vacuum. The residue was purified by chromatography on a silica gel chromatography (petroleum ether/ ethyl acetate = 8:1 to 4:1) to give corresponding products h1 – h22 (yield 75% – 89%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1805-32-9, its application will become more common.
