Yield: 100%
Reaction Conditions:
with ammonium formate;palladium 10% on activated carbon in methanol at 50; for 1 h;
Steps:
tert-Butyl (3S,42?)-4-(benzylarnino)-3 -fluoropiperidine- 1 -carboxylate (Intermediate 28; 711 mg), ammonium formate (582 mg), and 10% Pd/C (200 mg) in MeOH (10 ml) was heated to 50 °C for 1 h. The reaction mixture was cooled to room temperature, filtered through diatomaceous earth and concentrated under reduced pressure to give the title compound (503 mg, quantitative).NMR (CDCl3): 1.40 (s, 9H); 1.88 (m, 2H); 3.01 (m, 2H); 3.55 (m, 2H); 3.77 (m, IH); 4.66 (d, IH).
