Reaction Steps

A mixture of tert-butyl N-[(4aS,11bR)-3,3,6,6,11b-pentamethyl-10-nitro-4,4-dioxo-4a,5-dihydro-[1]benzoxepino[4,5-b][1,4]thiazin-2-yl]-N-tert-butoxycarbonyl-carbamate (70 mg, 0.120 mmol) (Prepared following the procedure for Intermediate 31 (trans), Step 1 and 2) and 10% Pd/C (38.6 mg, 0.036 mmol) in EtOAc (1.1 mL) and MeOH (1.1 mL) was stirred under hydrogen atmosphere for 16 hours. The mixture was passed through a celite cake and rinsed with ethyl acetate and ethanol. The filtrate was concentrated in vacuo to afford the title compound (66 mg, 0.120 mmol, 100% yield) as a white foam. MS m/z=574.3 (M+Na).
