To a solution of (1R,2S,7R,8S)-5-(7-azidomethyl-1,1-dioxo-1,4-dihydro-1λ6-thieno[2,3-e][1,2,4]thiadiazin-3-yl)-3-(4-fluoro-benzyl)-6-hydroxy-3-aza-tricyclo[6.2.1.02,7]undec-5-en-4-one (0.10 g, 0.19 mmol) in ethanol (6 mL) and ethyl acetate (3 mL) was added 10% palladium on carbon (10 mg). The mixture was degassed and stirred under an atmosphere of hydrogen gas (balloon) overnight. The resulting mixture was diluted with N,N-dimethylformamide (10 mL) and filtered through a pad of Celite. The organic was concentrated in vacuo to afford the crude product, (1R,2S,7R,8S)-5-(7-aminomethyl-1,1-dioxo-1,4-dihydro-1λ6-thieno[2,3-e][1,2,4]thiadiazin-3-yl)-3-(4-fluoro-benzyl)-6-hydroxy-3-aza-tricyclo[6.2.1.02,7]undec-5-en-4-one (95 mg, 0.19 mmol, 100%), which was used in the next step without further purification.
