Procedure

A solution of 7.79 g (13.23 mmol) of the intermediate obtained in Step A in 200 mL of methanol containing 0.9 g of 5% palladium on carbon was hydrogenated at 40 psi. When the uptake of hydrogen was complete, the catalyst was removed by filtration through Celite. The filtrate was concentrated under vacuum to yield 6.6 g (11.9 mmol, 90%) of product. FAB-MS: calculated for C33H4N4O4 556; found 557(M+H). 1H NMR (400 MHz, CDCl3): 1.32 (s, 6H), 1.39 (s, 9H), 1.87 (m, 1H), 2.51 (dd, 1H), 2.59 (m, 1H), 4.51 (m, 1H), 4.89 (d, 1H), 5.15 (d, 1H), 5.32 (br s, 1H), 6.71 (d, 1H), 6.81 (s, 1H), 7.21 (m, 10H).
