실험 절차

Trifluoroacetic acid (3.9 mL) was added to a solution of tert-butyl 4-(2-isopropylthiazole-5-carbonyl)-1-oxa-4,9-diazaspiro[5.5]undecane-9-carboxylate (example 113, step a) (0.765 g) in DCM (14.8 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 yellow oil. Yield 0.552 g.
