Reaction Steps

Add a solution of 50% sodium hydroxide in water (0.8 mL) to a solution of N-t-butoxycarbonyl-N-2-(3-chlorophenyl)ethyl-3-hydroxybenzylamine (46.7 mg, 0.129 mmol), n-propyl iodide (0.17 gm. 1.00 mmol), and tetrabutylammonium bromide (18 mg, 0.057 mmol) in toluene (1 mL). Stir the mixture at 1200 rpm and heat at 50-54° C. After 64.5 hour pour the mixture into 5 mL of water, separate the phases and extract the aqueous phase twice with dichloromethane. Combine the organic phases and wash with saturated sodium bicarbonate solution, and then saturated brine, dry (MgSO4), and concentrate to give a residue. Chromatograph the residuc on silica gel to give the title compound: MS (ES+): m/e (M+1) 404. TLC (20% EtOAc in hexanes, Rf 0.54).
