To a solution of (S)-1-(4-bromo-phenyl)-ethyl amine (3.58 g, 0.018 mol) in dry CH3CN (350 mL) was added 3-((1S)-1-(4-bromophenyl)ethyl)-7-(2-methylallyl)-7-phenyl-1,3-oxazepan-2-one (4.2 g, 0.018 mol), KI (3.19 g, 0.019 mol), and K2CO3 (3.73 g, 0.027 mol). The mixture was stirred at reflux overnight, filtered, and concentrated to give the crude product, which was purified by column chromatography to give 7-((1S)-1-(4-bromophenyl)ethylamino)-2-methyl-4-phenylhept-1-en-4-ol (2.2 g, 30%) as an oil.
