Reaction Steps

To a solution of 11-2 (6.0 g, 22.0 mmol) in 50 mL DMF at 0° C. was added NaH gradually. After the mixture was stirred for 40 min, CH3I (3.4 g, 24.0 mmol) was added in one portion. The reaction mixture was stirred for 5 hr, treated with 300 mL water and extracted three times with ethyl ether. The combined organic layers were washed with brine and dried over Na2SO4. After solvent removal, the residue was purified by silica gel flash chromatography (CHCl3 /hexanes 6:1) to afford the desired product 11-3 as a solid.
