Reaction Steps
Under an atmosphere of nitrogen, (2-hydroxy-ethyl)-carbamic acid tert-butyl ester (584 mg, 3.62 mmol) and triphenylphosphine (951 mg, 3.63 mmol) were added to a solution of ortho-methoxyphenol (500 mg, 4.03 mmol) in THF (8 ml). Subsequently, diethyl azodicarboxylate (772 mg, 4.44 mmol) was added at 0° C. and the reaction mixture was then stirred for 3 h at r.t. The solvent was evaporated under reduced pressure, the residue was taken up in ethyl acetate, washed (H2O), and dried (Na2SO4). Chromatographic purification gave the title compound (320 mg, 30%).
