Reaction Steps
A mixture of tert-butyl 3-((4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (400 mg, 0.949 mmol, 1 equiv), 4,4′-(4-chlorobutane-1,1-diyl)bis(fluorobenzene) (222.06 μl, 0.949 mmol, 1 equiv), potassium carbonate (393.5 mg, 2.847 mmol, 3 equiv), and sodium iodide (42.7 mg, 0.285 mmol, 0.3 equiv) in 2-butanone was stirred at 81° C. for 16 h. After cooling, the reaction mixture was filtered, filtrate concentrated, and the crude residue was purified using the Biotage flash chromatography system (SNAP 50 g cartridge, Rf=0.5, gradient—1%-10% methanol in dichloromethane) to afford the title compound as a white crystalline solid (500 mg, 80.8%); 1H NMR (400 MHz, DMSO-d6): δ 1.35 (bs, 2H); 1.51 (s, 9H); 1.59 (d, 2H, J=13.2 Hz); 2.02-2.04 (m, 2H); 2.36 (bs, 2H); 2.52-2.53 (m, 2H); 2.64-2.67 (m, 4H); 4.11 (s, 1H); 4.57 (s, 2H); 4.60 (s, 2H); 6.75 (bs, 1H); 6.81 (d, 2H, J=8.4 Hz); 7.08-7.12 (m, 4H); 7.16-7.20 (m, 2H); 7.32-7.36 (m, 4H); 7.49-7.53 (m, 2H); 7.78 (bs, 1H); 7.82-7.84 (m, 1H); MS for C4iH45F2N3O3 m/z 666.18 (M+H)+.
