Reaction Steps
Sodium bis-(trimethylsilyl)amide (440 mL 0.44 mol 1.0 M in THF) was cooled to −70° C. under a nitrogen atmosphere. A solution of 4-benzyloxybenzaldehyde (85 g, 0.4 mol) and methyl methoxyacetate (52 g, 0.5 mol) in THF (0.5 L) was added dropwise at −70° C. over 2 hours, and the mixture was stirred for an hour. A solution of concentrated HCl (85 mL) and water (85 mL) was added at −70° C. The resulting solution was allowed to warm to ambient temperature and was extracted with MTBE (2×0.5 L). The combined extracts were washed with brine (0.5 L), dried (MgSO4), filtered, and concentrated under to give 133 g of a red oil.
