Water → Methyl 2-(methoxymethyl)-2'-methyl-[1,1'-biphenyl]-4-carboxylate

Participants

Reaction Steps

Methyl 4-bromo-3-(methoxymethyl)benzoate obtained in step 2 (40 g; 154.38 mmol; 1 eq.), o-tolylboronic acid (23.09 g; 169.82 mmol; 1.10 eq.), K2CO3 (106.68 g; 771.90 mmol; 5 eq.), tetrakis(triphenylphosphine)palladium (0) (1.78 g; 1.54 mmol; 0.01 eq.) were taken up in toluene (200 mL) and water (200 mL) under nitrogen atmosphere. The reaction mixture was purged with vacuum, then degassed with nitrogen and then refluxed for 1 hour. The reaction mixture was cooled to room temperature, filtered over a pad of celite and washed with EtOAc (1000 mL). The filtrate was concentrated to afford a yellow oil which was taken in EtOAc (800 mL). The organic layer was washed with a saturated aqueous solution of NaHCO3 solution (250 mL), water (250 mL) and brine (250 mL), dried over MgSO4 and concentrated affording the title compound as a yellow oil used without further purification (41.9 g, quantitative). HPLC (Method A) Rt 5.34 min (Purity: 89.4%).
