Reaction Steps

A solution of 0.49 g (1.14 mmol) of benzyl ((8S,11R)-8-isopropyl-10-oxo-6-oxa-1,9,14-triazabicyclo[11.2.1]hexadeca-3,13(16),14-trien-11-yl)carbamate from step C in 80 ml of methanol was hydrogenated over 0.12 g of palladium on carbon (10%) under a hydrogen atmosphere under autogenous pressure at RT. After the starting material had completely reacted, the mixture was filtered and concentrated. The residue was purified by preparative HPLC. 0.06 g of the title compound was obtained.
