Reaction Steps
Intermediate (18c) (7.4 g, 15.0 mmol) was dissolved in EtOAc (200 mL), followed by the addition of sulfuric acid (1.50 mL). 10% Pd/C, Degussa type, wet 50% (0.05:0.45:0.5, palladium:carbon black:water, 16.0 g) was then added and the mixture was degassed with nitrogen and then stirred at room temperature under hydrogen for 2 hours. The mixture was then degassed with nitrogen, the palladium was filtered off under nitrogen and the resulting material was concentrated to obtain the title compound as a pale yellow oil (6.5 g). Anal. HPLC retention time=3.2 minutes. Gradient conditions: 10% solvent B/90% solvent A to 90% solvent B/10% solvent A over 6 minutes. MS m/z: [M+H+] calcd for C27H34FN3O3, 468.27; found 468.4. 1H-NMR (DMSO-d6) 7.67 (1H, d), 7.54 (1H, t), 7.33 (1H, t) 7.10 (1H, d), 7.03 (2H, d), 6.87 (1H, s), 5.08 (1H, s), 4.12 (2H, m), 4.00 (2H, s), 3.99 (2H, s), 3.48 (2H, s), 2.32 (2H, m), 1.62 (3H, m), 1.14 (9H, s), 0.85 (3H, t).
