Versuchsvorschrift

Trifluoroacetic acid (3.8 mL) was added to a solution of tert-butyl 4-(2-phenylthiazole-4-carbonyl)-1-oxa-4,9-diazaspiro[5.5]undecane-9-carboxylate (example 112, step a) (0.85 mg) in DCM (15.2 mL). The resulting mixture was stirred at RT for 1 h. Toluene (30 mL) was added and the mixture was evaporated in vacuo. The yellow residue was dissolved in MeOH and applied to a SCX cartridge pre-wetted with MeOH. The cartridge was washed with MeOH and eluted with 2M ammonia in MeOH. The eluent was evaporated in vacuo to give the subtitled compound as a brown oil. Yield 0.629 g.
