Procedure

A mixture of tert-butyl 1-oxo-2,8-diazaspiro[4.5]decane-8-carboxylate (150 mg, 0.590 mmol), 4-fluoro-2-methyl-5-oxo-2,5-dihydrofuran-3-yl trifluoromethanesulfonate (148 mg, 0.590 mmol), xantphos (34.1 mg, 0.059 mmol), water (0.032 mL, 1.77 mmol) in toluene (20 mL) was degassed by nitrogen followed by addition of palladium acetate (6.6 mg, 0.029 mmol). The resulting mixture was heated at 65° C. overnight. After filtration through CELITE®, the filtrate was concentrated and the residue was purified on silica gel column using ethyl acetate and hexane as eluting solvents to give the title compound. LCMS: (M+1)+: 355.15.
