4-(PYRIMIDIN-5-YL)BENZALDEHYDE Chemical Properties,Uses,Production

Uses

4-(Pyrimidin-5-yl)benzaldehyde is a useful reactant and reagent in organic reactions such as the synthesis of 1,2-difluorination of alkenes, and β-Cyanoacrylamides.

Synthesis

5-Bromopyrimidine

4595-59-9

4-Formylphenylboronic acid

87199-17-5

4-(PYRIMIDIN-5-YL)BENZALDEHYDE

198084-12-7

To a stirred solution of 5-bromopyrimidine (1 eq.), 4-formylphenylboronic acid (1.3-3.0 eq.), and sodium carbonate monohydrate (1.3-3.0 eq.) in a mixed solvent of dimethoxyethane/water (4:1, v/v) (concentration of about 0.05-0.2 M) was added tetrakis(triphenylphosphine)palladium (Pd(PPh3)4, 0.1 eq.). The reaction mixture was stirred at 90 °C for about 18 h and subsequently quenched with water. The mixture was extracted with dichloromethane (CH2Cl2) according to standard post-treatment steps and the organic layer was dried over anhydrous sodium sulfate (Na2SO4) or anhydrous magnesium sulfate (MgSO4), filtered and concentrated under reduced pressure. The crude product was purified by fast column chromatography or silica gel radial chromatography. According to the above general method, 4-(5-pyrimidinyl)benzaldehyde (162 mg, 99% yield) was obtained from 5-bromopyrimidine (199 mg, 1.25 mmol) and 4-formylphenylboronic acid (469 mg, 3.13 mmol).
