Potassium Iodide → Methyl 4-{[(2-{5-fluoro-2-[(4'-methyl-1,1'-biphenyl-4-yl)methoxy]phenyl}ethyl)(5-methoxy-5-oxopentyl)amino]methyl}benzoate

Participants

Reaction Steps

447 mg (0.93 mmol) of methyl 4-({(5-methoxy-5-oxopentyl)[2-(5-fluoro-2-hydroxyphenyl)ethyl]amino}methyl)benzoate from Ex. XII and 277 mg (1.02 mmol) of 4-(chloromethyl)-4′-(trifluoromethyl)-1,1′-biphenyl are dissolved in 10 ml of acetonitrile. 455 mg (1.40 mmol) of caesium carbonate and a spatula tip of potassium iodide are added, and the mixture is heated at reflux for 48 hours. The suspension is filtered and concentrated and the residue is chromatographed over silica gel using cyclohexane:ethyl acetate (5:1).
