Reaction Steps

To a solution of 4-bromo-5-chloro-N-((1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-{[2-(trifluoromethyl)phenyl]methyl}ethyl)-2-thiophenecarboxamide (260 mg, 0.46 mmol) in THF (5 mL) was added Na2CO3 (2N, 0.7 mL, 1.4 mmol), Pd(dppf)Cl2 (40 mg, 48 μmol) and 1,4-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (303 mg, 1.38 mmol). The reaction mixture was heated to 75° C. in a sealed tube under N2. After 8 h, the reaction mixture was concentrated under vacuum and purified on silica (10:1 CHCl3/MeOH) to afford the title compound (196 mg, 73.4%): LC-MS (ES) m/z=587 (M+H)+.
