10% Cd/Pb couple (1.25 g, 10 mmol Cd) was added to a rapidly stirring solution of the Troc-carbamate, 119 (1.00 g, 2.1 mmol) in a mixture of THF (13 mL) and 1N NH4OAc (B mL). Upon addition, the reaction mixture went cloudy. After 40 minutes, TLC showed the reaction to be complete and the reaction mixture was diluted with EtOAc (200 mL). The solution was dried over anhydrous MgSO4 and the solids were filtered and rinsed with EtOAc (50 mL). Evaporation of the solvent yielded the product as a yellow glass (0.581 g, 2.0 mmol). 1H NMR (270 MHz, CDCl3) δ 7.73 (d, 1H, J=4.57 Hz), 7.08 (s, 1H), 4.0-3.4 (m, 12H), 2.4-1.8 (m, 4H).
