Reaction Steps

The compound (V) was reacted with triphenylphosphine (PPh3) in a suitable solvent such as tetrahydrofuran followed by addition of a catalytic amount of water to provide corresponding amine. This amino compound was further treated in situ with di-tert-butyl dicarbonate ((Boc)2O) in presence of a suitable base such as triethylamine to provide an amino protected compound, (2S, 5R)-2-(tert-butoxycarbonylaminomethyl)-6-benzyloxy-7-oxo-1, 6-diaza-bicyclo[3.2.1] octane (VI). The intermediate compound of Formula (VI) was subjected to hydrogenolysis using a catalyst such as 5% or 10% Palladium on carbon in presence of a hydrogen source such as hydrogen gas and in a suitable solvent such as methanol to provide debenzylated compound, (2S, 5R)-2-(tert-butoxycarbonylaminomethy)-6-hydroxy-7-oxo-1,6-diaza-bicyclo[3.2.1] octane (VII).
