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 (2x50 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), 6.894.70 (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.
