Versuchsvorschrift

Trifluoroacetic acid (15 mL) was added to a stirred solution of tert-butyl 4-(2,2,2-trifluoroacetyl)-1-oxa-4,9-diazaspiro[5.5]undecane-9-carboxylate (example 12, step c) (1 g) in DCM (15 mL) at 20° C. The resulting solution was stirred at 20° C. for 10 minutes. Toluene (50 mL) was added and the solvents were evaporated under reduced pressure to afford the subtitled compound. Yield 1.4 g.
