Participants

Reaction Steps

The product from Step B (3.75 g, 11.3 mmol) was dissolved in methanol (75 mL) in a Parr bottle, and the vessel purged with argon. To this was added 10% palladium on carbon (0.80 g) and the reaction hydrogenated under 60 psi hydrogen for 24 h. The catalyst as removed by filtration through Celite, and the filtrate evaporated in acuo to give the title compound as an oil. 1HNMR (300 MHz, CDCl3) δ 4.08 (1H, br s), 3.90 (1H, d, J=12 Hz), 2.5-3.8 (6H, m), 1.80 (1H, m), 1.60 (1H, m), 1.46 (9H, s), 1.30 (4H, m),0.90 (3H, t, J=7 Hz).
