Reaction Steps
A mixture of tert-butyl 1-oxo-2,8-diazaspiro[4.5]decane-8-carboxylate (200 mg, 0.786 mmol), 2-methyl-5-oxo-2,5-dihydrofuran-3-yl trifluoromethanesulfonate (232 mg, 0.944 mmol), Xantphos (45.5 mg, 0.079 mmol), palladium (II) acetate (8.83 mg, 0.039 mmol), water (0.043 mL, 2.359 mmol), and potassium carbonate (217 mg, 1.573 mmol) in toluene (20 mL) was degassed by nitrogen and heated at 65° C. for 16 h. 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. LC/MS: (M+1)+: 351.15.
