Reaction Steps
Powdered potassium carbonate (5.18 g, 37.7 mmol) is added to a stirred solution of 4-cyanophenol (2.00 g, 16.8 mmol) and bromoacetaldehyde diethyl acetal (4.53 mL, 30.3 mmol) in anhydrous DMF (20 mL). The resultant mixture is stirred at 85° C. under nitrogen for 3 days. The mixture is cooled to ambient temperature; then water (100 mL) and EtOAc (100 mL) are added to the mixture. The organic layer is separated, dried over MgSO4, filtered and concentrated. The oil is chromatographed on silica (gradient 5-20% EtOAc in hexane) to give 2.80 g (11.9 mmol, 71% yield) of the title compound. 1H NMR (CDCl3): δ1.24 (t, J=7.1 Hz, 6H), 3.60-3.68 (m, 2H), 3.73-3.81 (m, 2H), 4.04 (d, J=5.2 Hz, 2H), 4.83 (t, J=5.2 Hz, 1H), 6.97 (br d, J=9.2 Hz, 2H), 7.58 (br d, J=9.2 Hz, 2H); Analysis for C13H17NO3: calcd: C, 66.36; H, 7.28; N, 5.95; found: C, 66.41; H, 7.34; N, 6.01.
