실험 절차

A mixture of tert-butyl 4-((2-((2S)-bicyclo[2.2.1]heptan-2-ylamino)-5-methyl-4-oxo-4,5-dihydrothiazol-5-yl)methyl)piperidine-1-carboxylate (1.42 g, 3.37 mmol, 1.0 eq) in 50 mL of a 4.7 M HCl solution in EtOAc was stirred at roomtemperature. After 4 h, the reaction mixture was concentrated in vacuo. Aqueous Na2CO3 (2.0 M, 20 mL) was then added, and water was removed in vacuo. The residue was then triturated with 10% MeOH—CH2Cl2 (6×100 mL), and the combined triturating solution were concentrated in vacuo. The crude product was dissolved in CH2Cl2, filtered, and concentrated in vacuo to afford the title compound as a light orange solid (1.08 g). MS (ESI, pos. ion) m/z: 322 (M+H).
