Procedure
Dried potassium fluoride (19.51 mg, 0.336 mmol) and copper(I) iodide (64.0 mg, 0.336 mmol) were mixed and heated to 200° C. under gentle shaking at reduced pressure (1 Torr) until a light yellow-greenish color appeared. After cooling, anhydrous N-methyl-2-pyrrolidinone (1 mL) was added, followed by (S)-2-(1-((9-iodo-4,6-dimethyl-5-oxo-5,6-dihydrobenzo[c][2,7]naphthyridin-8-yl)oxy)-4-methylpentan-2-yl)isoindoline-1,3-dione (100 mg, 0.168 mmol) and trimethyl(trifluoromethyl)silane (0.075 mL, 0.504 mmol). The brown solution thus obtained was heated at 90° C. for 16 h. After cooling, aqueous ammonia (10 mL) was added to the reaction mixture. The reaction mixture was and extracted with ethyl acetate (3×10 mL). The combined organic layers were washed with brine (1×10 mL), dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by preparative TLC (50% ethyl acetate: petroleum ether as eluent system) to afford (S)-2-(1-(4,6-dimethyl-5-oxo-9-(trifluoromethyl)-5,6-dihydrobenzo[c][2,7]naphthyridin-8-yloxy)-4-methylpentan-2-yl)isoindoline-1,3-dione (80 mg, 0.033 mmol, 20% yield, 22% purity) as a pale yellow solid. LC/MS (ESI) m/e 538.6 [(M+H)+, calcd for C29H27F3N3O4 538.2] LC/MS retention time (method E): tR=1.27 min.
