Procedure

Into a 8-mL round-bottom flask, was placed a solution of tert-butyl 3-(2-(2-(2-(methylamino)ethoxy)ethoxy)ethoxy)propanoate (89.3 mg, 0.31 mmol, 1.00 equiv) in N,N-dimethylformamide (6 mL), potassium carbonate (84.7 mg, 0.61 mmol, 1.99 equiv), potassium iodide (10.2 mg, 0.06 mmol, 0.20 equiv), and N-(3-(trifluoromethyl)benzyl)-2-(2-(3-(bromomethyl)benzamido)-5-(piperidin-1-yl)phenyl)isonicotinamide (200 mg, 0.31 mmol, 1.00 equiv). The resulting solution was stirred overnight at 70° C. The solids were filtered out. The resulting mixture was concentrated under vacuum. The residue was dissolved in 20 mL of dichloromethane. The resulting mixture was washed with 2×20 mL of water. The resulting mixture was washed with 1×20 mL of brine, dried over sodium sulfate, and concentrated under vacuum. This resulted in 264 mg (crude) of product as yellow oil.
