Versuchsvorschrift

4-Bromophenol (0.2 g, 1.16 mmol) and (S)-(+)-1-dimethylamino-2-propanol (0.14 ml, 1.16 mmol) were dissolved in dichloromethane (10 ml). PS-Triphenylphospine (1.74 g, 1.74 mmol) was added, followed by di-tert-butyl azodicarboxylate (0.4 g, 1.74 mmol). The mixture was stirred overnight at room temperature, then filtered and the filtrate washed with sodium hydrogenocarbonate then brine. The organic phase was dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the desired product. Yield: 0.3 g, 100%. LCMS method: 2, RT: 2.62 min; MI: 258-260 [M+1].
