Reaction Conditions

Reaction Steps

To a solution of 1.1 g (0.00953 mol) of 5benzyloxy-2-(3-benzyloxy-phenyl-1-[4-(2-chloro-ethoxy)-benzyl]-3methyl-1H-indole (example No. 58) in 10 mL of DMF was added 1.1 mL (0.0112 mol) of piperidine, and 0.93 g (00561 mol) of potassium iodide. The reaction mixture was heated to ˜40-50° C. for 4 hours. After cooling the reaction mixture to room temperature, 150 mL of ethyl acetate were added and the mixture was washed with water (3×100 mL). The organic solution was collected, washed with saturated brine, removed, dried over magnesium sulfate, filtered and evaporated to yield 1.0 g of product of the product after purification.
