To a solution of NaHMDS (1.1 eq) in dry THF at −78° C. a mixture of 4-Benzyloxy-3-methyl-benzaldehyde (1 eq) and Methoxy-acetic acid methyl ester (1.25 eq) in THF were added dropwise and the mixture reaction at this temperature over 1.5 hours. Then the reaction was quenched with HCl 3N and allowed to rise room temperature. Washed with brine and extracted with ether. The organic layer was dried and concentrated to dryness to give after chromatography in silica gel the title product.
