Reaction Steps

To a 1l round bottomed flask with a stirring bar and an argon inlet was added 3-bromo-4-(2-methoxyethoxy)-5-methoxybenzaldehyde (12.00 g, 41.50 mmol) and dry THF (150 mL). This solution was cooled in an ice bath and phenylmagnesiumbromide in diethyl ether (16.6 mL of a 3.0 M solution, 49.81 mmol) was added with a syringe. The resulting solution was stirred for 1 h at 0° C. The reaction was quenched with aqueous NH4Cl solution. The mixture was diluted with EtOAc and the layers were separated. The organic phase was washed with brine, dried (MgSO4), filtered and concentrated in vacuo. This material was chromatographed on 400g of silica gel using 30/70 EtOAc-hexane as eluant. There was obtained 1-(3-bromo-4-(2-methoxyethoxy)-5-methoxyphenyl)-1-phenylmethanol as an oil. 1H NMR (CDCl3): δ2.29 (d, j=4Hz, 1H); 3.44 (s, 3H); 3.74 (t, j=4 Hz, 2H); 3.82 (s, 3H); 4.13 (t, j=4 Hz, 2H); 5.75 (d, j=4Hz, 1H); 6.88 (s, 1H); 7.12 (s, 1H); 7.35 (m, 5H).
