Reaction Conditions

Reaction Steps

To a solution of 7A (4.4 g, 23 mmol) and K2CO3 (6.4 g, 46 mmol) in DMF (30 mL) was added ethyl iodide (2.49 mL, 31 mmol) at rt. The mixture was heated at 50° C. for 2.0 h. After cooling to rt, it was diluted with ether, washed with water and brine, dried over MgSO4. The crude residue was purified by flash column chromatography (EtOAc:hexanes=1:5) to give 3.86 g (77%) of 9A as viscous oil. 1H NMR (400 MHz, CDCl3) δ ppm 1.47 (m, 3H) 4.00 (m, 2H) 6.96-7.08 (m, 3H).
