Reaction Steps

To a mixture of compound PPP, (3-iodo-4-methyl-phenyl)-methanol, (4 g, 16.12 mmol) and phenylboronic acid (2.06 g, 16.89 mmol) in 1-propanol (30 mL) was successively added palladium(II) acetate (0.01276 g, 0.05 mmol), triphenyl phosphine (0.042 g, 0.161 mmol), aq. sodium carbonate solution (2 M, 11.44 mL, 22.88 mmol), and water (6 mL). The mixture was heated to 100° C. until reaction is complete (tlc), cooled, quenched with water (20 mL) and extracted into ethyl acetate (3×50 mL). Combined organic layer was washed with 2% aq. sodium bicarbonate (2×25 mL), brine (1×50 mL), dried (MgSO4) and concentrated to yield 2.82 g of (6-methyl-biphenyl-3-yl)-methanol, compound QQQ, that was directly taken into next step without any further purification; Rt: 10.95 min.
