To a solution of tert-butyl (4S,7R,10aS)-7-ethyl-5-oxooctahydro-2H-pyrido[2,1-b][1,3]thiazepin-4-ylcarbamate (52 mg, 0.16 mmol) in DCM (1 mL) was added TFA (1.0 mL, 13 mmol). The reaction mixture was stirred at rt for 1 hr. The reaction mixture was concentrated and dried under high vacuum to afford (4S,7R,10aS)-4-amino-7-ethylhexahydro-2H-pyrido[2,1-b][1,3]thiazepin-5(7H)-one trifluoroacetate (54 mg, 0.16 mmol, 100% yield) as an oil. Anal. Calcd. for C11H20N2OS m/z 228.3. found: 229.2 (M+H)+.
