Procedure

To a solution of 4-bromo-N-((1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-{[2-(trifluoromethyl)phenyl]methyl}ethyl)-2-thiophenecarboxamide (200 mg, 0.37 mmol) in dioxane/H2O (5:1, 6 mL) was added K2CO3 (0.17 g, 1.23 mmol), tetrakistriphenylphosphine Pd(0) (42 mg, 0.036 mmol) and 1,4-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (413 mg, 1.86 mmol) [from Preparation 17]. The reaction mixture was heated to 80° C. in a sealed tube for 2 h. The reaction solution was concentrated under vacuum, and purified on silica gel (10-50% EtOAc/Hex) to give the title compound (192 mg, 94%) as a white solid: LC-MS (ES) m/z 553 (M+H)+.
