Versuchsvorschrift
0.40 g (1.4 mmol) 2-methoxy-4,5,7,8-tetrahydro-thiazolo[4,5-d]azepine-6-carboxylic acid tert-butyl ester, 1.3 mL trifluoroacetic acid in 2.5 mL dichloromethane (DCM) were stirred at RT overnight. The reaction was concentrated to dryness. DCM and a small amount of methanol (MeOH) were added to the residue and filtrated. The precipitate were isolated and 90 mg 3,4,5,6,7,8-Hexahydro-thiazolo[4,5-d]azepin-2-one trifluoro-acetic acid was obtained. Yield: 90 mg (23% of theory). ESI-MS: m/z=171 (M+H)+; Rt(HPLC): 0.15 min (Method J).
