Reaction Steps

A solution of Intermediate 84a (1.10 g, 3.29 mmol) in IMS (25.0 mL) was added to palladium on charcoal (10 wt %, 110 mg) and the reaction stirred under H2 for 1 h. The mixture was filtered through Celite and evaporated in vacuo to give the title compound (840 mg, 99%). 1H NMR (300 MHz, d4-MeOD): 1.48 (9H, s), 1.91 (1H, m), 2.02-2.24 (2H, m), 2.41 (1H, m), 2.74 (2H, t, J 7.1), 3.13 (1H, ddd, J 11.1, 10.2, 7.0), 3.32-3.53 (2H, m), 3.72 (1H, ddd, J 11.0, 7.2, 3.5), 3.89 (1H, dd, J 9.5, 5.3).
