Participants

Reaction Steps

A solution of (2S, 4S)-1-p-methoxybenzyloxycarbonyl-2-azidomethyl-4-tritylthiopyrrolidine (17.27 g: 30.64 mmole) in a mixture of ethyl acetate (150 ml), methanol (200 ml), and acetic acid (2.63 ml: 46 mmole) is subjected to conventional hydrogenation over 5% palladium on carbon (5 g). After the reaction, the catalyst is filtered off and the filtrate is concentrated in vacuo to give (2S,4S)-1-p-methoxybenzyloxycarbonyl-2-aminomethyl-4-tritylthiopyrrolidine acetate (17.33 g) as a residue. The residue is dissolved in dichloromethane, washed with aqueous sodium hydrogen carbonate, and concentrated to give (2S,4S)-2-aminomethyl-1-p-methoxybenzyloxycarbonyl-4-tritylthiopyrrolidine (16.82 g).
