Reaktionsschritte

To methyl 5-bromo-3-iodobenzoate (Step A above) (5.01 g, 0.015 mole) in anhydrous methylene chloride (100 mL) at -78° C., was added dropwise minutes, diisobutylaluminum hydride (5.50 mL, 0.03 mole). The mixture was stirred for 1 hour then allowed to warm to 0° C. The reaction solution was poured into 600 mL, chilled 3N HCl and extracted 3× with methylene chloride (150 mL). The organic layers were combined, dried over MgSO4 and concentrated under vacuum to yield 5-bromo-3-iodobenzyl alcohol (4.54 g) as a white solid. MP=110-112° C. MS and NMR were consistent with the desired structure.
