Procedure
To a 50 mL round bottom flask containing (S)-2-allyl-1,3-dioxo-N-((4-(trifluoromethyl)phenyl)(3-(trifluoromethyl)pyridin-2-yl)methyl)isoindoline-5-carboxamide (Example 276) (160 mg, 0.300 mmol) was added EtOAc (15 mL). The resulting mixture was stirred at 23° C. for 2 min. At this time, Pd/C (10%, 50 mg) was added and hydrogen was bubbled through the mixture for 10 min. The reaction mixture was then left under 1 atm of hydrogen for 1 h. The solid was filtered off on a pad of Celite™ and eluted with EtOAc (75 mL). The solvent was evaporated to give (S)-1,3-dioxo-2-propyl-N-((4-(trifluoromethyl)phenyl)(3-(trifluoromethyl)pyridin-2-yl)methyl)isoindoline-5-carboxamide as a white solid. 1H NMR (300 MHz, CDCl3) δ ppm 8.93 (d, J=4.1 Hz, 1H), 8.42 (d, J=7.6 Hz, 1H), 8.30-8.19 (m, 2H), 8.11-8.01 (m, 1H), 7.91 (d, J=7.7 Hz, 1H), 7.64-7.45 (m, 5H), 6.88 (d, J=7.6 Hz, 1H), 3.68 (t, J=1.0 Hz, 2H), 1.72 (sxt, J=7.4 Hz, 2H), 0.95 (t, J=7.5 Hz, 3H). MS (ESI pos. ion) m/z: 536.2 (M+H).
