To a solution of 3-2 (2.0 g, 10.6 mmol) in dichloroethane (106 mL) was added triphosgene (3.16 g, 10.64 mmol). The reaction mixture was stirred at room temperature for 3 days. An off-white precipitate formed, which was washed with dichloroethane (100 mL) and dried in vacuo to give 2.03 g (89%) of 3-3 as a tan solid. LC/MS: m/z (M+H)=213.9.
