Participants

Reaction Steps

A solution of 5-(S)-aminomethyl-3-[4′-(N-methoxyamino)carbonyl-3′-fluorophenyl]-oxazolidine-2-one (0.053 ml, 0.47 mmol), triethylamine (0.12 ml, 0.84 mmol) and ethyl dithioacetate (0.87 ml, 7.6 mmol) in DMF (0.75 ml) was stirred at r.t. for 48 h. Solvent was removed under vacuum, and the crude material purified by silica gel PTLC (eluent: 5% MeOH in ethyl acetate). White crystalline solid (100 mg, 70%). HPLC Rt=4.6 min. MS (m/z): [M+H]+=342.
