Potassium Carbonate → 4-(4-Acetyl-3-chlorophenoxy)benzonitrile

Participants

Reaction Steps

To a solution 4-cyanophenol (CAS Reg. No. 767-00-0, 1.2 g), 2-chloro-4-fluoroacetophenone (CAS Reg. No. 700-35-6, 1.7 g) in DMA (10 ml) was added K2CO3 (1.66 g). The mixture is refluxed for 5 h. TLC (heptane/EtOAc 2:1) showed complete conversion. Water was added and the mixture was extracted with DCM. The combined organic layers were dried over Na2SO4 and then concentrated to an oil. The residue was purified by flash chromatography (SiO2, EtOAc/heptane 1:2) to give the title compound (1.8 g) as yellow oil. MS (m/e)=272.2 [M+H+].
