Reaction Steps

Benzyl (2S,4R)-4-(benzyloxy)-2-isopropenylpyrrolidine-1-carboxylate (1.00 g, 2.84 mmol) was dissolved in ethanol (40 mL) and then 5% Pd—C (100 mg) was added to the solution. The flask was purged with hydrogen and then shaken on a Parr under 53 psi atmosphere of hydrogen for 17 hours. The reaction was then flushed with nitrogen and filtered through Celite on a glass frit and washed with methanol. The filtrate was concentrated and chromatographed on silica gel (1% triethylamine/10% methanol/89% ethyl acetate) to furnish the amine as a pale yellow oil, 0.53 g (85%). LC/MS (M+H)+ m/z=220.2; 1H NMR (CDCl3) 7.33 (m, 5H), 4.49 (m, 2H), 4.12 (m, 1H), 3.19 (dd, 1H), 3.00 (m, 2H), 2.05 (m, 1H), 1.96 (bs, 1H), 1.49 (m, 2H), 1.00 (d, 3H), 0.91 (d, 3H).
