1,2-Dimethoxyethane → HCID 59840902, compound

Participants

Reaction Steps

4,6-dichloropyrimidine (6.0 g, 40 mmol) and 2-benzyloxyphenylboronic acid (6.61 g, 29 mmol) were added to a solution of dimethoxyethane (120 mL) and water (18 mL), followed by the addition of NaHCO3 (6.72 g, 80 mmol) and (PPh3)2PdCl2 (0.84 g). To this end the reaction mixture was allowed to reflux for 8 h, and the solvent removed under reduced pressure. The residue was taken up in CH2Cl2 (100 mL), and the resulting solution washed with water, dried over anhydrous K2CO3, filtered and the solvent removed under reduced pressure. The crude product was purified by flash chropatography on silica gel (eluent CH2Cl2) and recrystallized from hexanes yielding 4-chloro-6-(2-benzyloxyphenyl)-pyrimidine (6.88 g; 80%) as white powder.
