실험 절차

Trifluoroacetic acid (66 mL) was added to a solution of tert-butyl 4-(2,2,2-trifluoroacetyl)-1-oxa-4,9-diazaspiro[5.5]undecane-9-carboxylate (example 101, step d) (4.33 g) in DCM (66 mL) and the resulting mixture was stirred at RT for 20 min. Toluene (50 mL) was added and the mixture was evaporated in vacuo (×3) to give the subtitled compound. Yield 5.52 g.
