Reaction Steps

To a solution of N-[2-(4-bromo-phenyl)-2-hydroxy-2-(3-methoxy-phenyl)-ethyl]-2-chloro-acetamide (3.67 g, 9.2 mmol), in benzene (205 mL) at room temperature was added t-BuOK (4.54 g, 40.5 mmol). The reaction mixture was stirred at room temperature for 2 h. To the mixture was added water (40 mL) and the aqueous layer was washed with CH2Cl2 (2×50 mL). The combined organic extracts were dried over MgSO4 and concentrated. Purification by flash chromatography with hexanes/EtOAc (3:1) afforded 3.34 g of 6-(4-bromo-phenyl)-6-(3-methoxy-phenyl)-morpholin-3-one. 1HNMR (400 MHz, CDCl3) δ 7.46-7.41 (comp, 2H), 7.27-7.17 (comp, 2H), 6.89-6.70 (comp, 3H), 6.69 (br, 1H), 4.10 (s, 2H), 3.93-3.80 (comp, 2H), 3.76 (s, 3H); MS (M+1) 362.1, 364.1.
