Reaction Steps

Tert-butyl N-[(4aR,6S,11bR)-3,3,6,11b-tetramethyl-10-nitro-4,4-dioxo-5,6-dihydro-4aH-[1]benzoxepino[4,5-b][1,4]thiazin-2-yl]-N-tert-butoxycarbonyl-carbamate (7.3 g, 12.86 mmol) and palladium on carbon (10%), wet (1 g, 0.470 mmol) were combined in ethyl acetate (60 ml) with 5 ml of MeOH under hydrogen atmosphere and stirred at room temp for 1 h. The solution was filtered thru celite, the Pd solids were washed with DCM and MeOH, then the organics were concentrated to afford tert-butyl N-[(4aR,6S,11bR)-10-amino-3,3,6,11b-tetramethyl-4,4-dioxo-5,6-dihydro-4aH-[1]benzoxepino[4,5-b][1,4]thiazin-2-yl]-N-tert-butoxycarbonyl-carbamate (6.5 g, 12.09 mmol, 94% yield) as a white solid. MS m/z=560 [M+Na].
