Procedure

A mixture of tert-butyl 3-((1-(4-fluorophenyl)-4-oxo-1,3,8-triazaspiro[4.5]decan-3-yl)methyl)benzoate (163.5 mg, 0.372 mmol, 1 equiv), 1-(3-chloropropyl)-3-cyclopropyl-1H-benzo[d]imidazol-2(3H)-one (93 mg, 0.372 mmol, 1 equiv), sodium iodide (22.3 mg, 0.15 mmol, 0.4 equiv) and potassium carbonate (102.8 mg, 0.74 mmol, 2 equiv) in 2-butanone was stirred at 81° C. for 16 h. After cooling the reaction mixture, the crude mixture was partitioned between ethyl acetate and water. The organic layer was dried over MgSO4, filtered, concentrated, and the crude residue was purified using the Biotage flash chromatography system (SNAP 10 g cartridge, Rf=0.5, gradient—1%-10% methanol in dichloromethane) to afford the title compound (166 mg, 68%); MS for C38H44FN5O4 m/z 654.24 (M+H)+.
