Reaction Steps

To a solution of tert-butyl N-[[4-[5-[3-[bis(tert-butoxycarbonyl)amino]-6-(1,4-dioxaspiro[4.5]dec-7-en-8-yl)pyrazin-2-yl]-1,3,4-oxadiazol-2-yl]phenyl]methyl]-N-methyl-carbamate (680 mg, 0.94 mmol) in THF (2.0 mL) was added 1M aqueous HCl (1.9 mL of 1 M, 1.9 mmol) and the reaction mixture was heated at 60° C. for 6 h. The reaction was cooled to room temperature and diluted with EtOAc, the layers were separated and the organic layer was washed once with aqueous NaHCO3, then once with brine, dried over Na2SO4, filtered and concentrated to dryness to yield tert-butyl N-[[4-[5-[3-[bis(tert-butoxycarbonyl)amino]-6-(4-oxocyclohexen-1-yl)pyrazin-2-yl]-1,3,4-oxadiazol-2-yl]phenyl]methyl]-N-methyl-carbamate (487 mg, 76%) and was used without further purification. LC/MS m/z 677.5 [M+H]+.
