Procedure

A mixture of tert-butyl 1-oxo-2,8-diazaspiro[4.5]decane-8-carboxylate (I-11) (200 mg, 0.786 mmol), 4-isopropyl-5-oxo-2,5-dihydrofuran-3-yl trifluoromethanesulfonate (259 mg, 0.944 mmol), Xantphos (46 mg, 0.079 mmol), palladium (II) acetate (8.8 mg, 0.039 mmol), water (0.043 mL, 2.4 mmol), and potassium carbonate (217 mg, 1.57 mmol) in toluene (20 mL) was heated at 66° C. for 16 h. After filtration through CELITE®, the filtrate was concentrated and the residue was purified on a silica gel column to give the title compound. LC/MS: (M+1)+: 379.21.
