To a solution of compound 7-((1S)-1-(4-bromophenyl)ethylamino)-2-methyl-4-phenylhept-1-en-4-ol (2.2 g, 5.5 mmol) in CH2Cl2 (50 mL) was added triphosgene (3.2 g, 11 mmol) and Et3N (1.7 g, 16.5 mmol) at 0° C. The mixture was stirred at room temperature overnight, and put at room temperature for 3 days, the volatile was evaporated. The resulting mixture was washed with 1 N aq HCl and extracted with CH2Cl2. The combined organic phase was dried over Na2SO4 and concentrated to give the crude final product, which was purified by chromatography to afford two isomers.
