Triphenylphosphine → 1-(1-Methyl-2-phenoxy-ethoxy)-naphthalene-2-carboxylic acid methyl ester

Participants

Reaction Steps

To a solution of 1.00 g 1-hydroxy-naphthalene-2-carboxylic acid methyl ester, 0.75 g 1-phenoxy-propan-2-ol and 3.89 g triphenyl phosphine in 60 ml dry THF at 0° C. 3.00 g diisopropylazodicarboxylate were added. After 48 h at room temperature the reaction was concentrated in vacuo, the residue was taken up in ethyl acetate, washed with sat. sodium hydrogen carbonate solution and dryed over magnesium sulphate. The solvent was removed in vacuo and after chromatography on silica (ethyl acetate/heptane) 0.47 g 1-(1-methyl-2-phenoxy-ethoxy)-naphthalene-2-carboxylic acid methyl ester were obtained.
