    • This aldehyde was prepared by heating 4-carboxybenzaldehyde to reflux in neat thionyl chloride until complete dissolution, removing all volatiles, and treating the residue with excess diethylamine in dichloromethane at 0°C. This procedure gives aldehyde 6 in 98% yield without need for further purification.

    • Prepared from 3-bromophenol. The silyl protecting group was affixed using t-butyldimethylsilyl chloride with imidazole in DMF. Treatment with n-BuLi in THF at -78°C, followed by addition to a stirring solution of magnesium bromide etherate in THF at 25°C generated the 3-(t-butyldimethyl-silyloxy)phenylmagnesium bromide
