Procedure
To a solution of the title compound of Step (A) (0.42 g, 1.75 mmol) in 5 mL of DMF at 50° C., anhydrous potassium carbonate (0.29 g, 2.09 mmol) and 1-bromo-3-phenyl propane (0.52 g, 2.63 mmol) were added and stirred for 15 hr. The mixture was then added to 25 mL water and the solution was extracted with 3×25 mL EtOAc. The combined organic extracts were washed with water and dried and evaporated. The residue thus obtained was chromatographed on 25 g of silica gel using 3:1 hexane:EtOAc to afford 0.32 g (51%) of the title compound of this step as a light yellow oil.
