The desired intermediate was prepared from the deprotection of 4-(2-fluorobenzyloxy)-N-(t-butoxycarbonyl)-N-(isopropyl)butylamine using standard techniques. The 4-(2-fluorobenzyloxy)-N-(t-butoxycarbonyl)-N-(isopropyl)butylamine was admixed with a 4:1 mixture of methylene chloride and trifluoroacetic acid. The progress of the reaction was monitored by thin layer chromatography.
