1-Methylpiperazine → 1-[(2S,4S)-1-allyloxycarbonyl-4-mercapto-2-pyrrolidinecarbonyl]-4-methylpiperazine

Participants

Reaction Steps

To a solution of (1S,4S)-5-allyloxycarbonyl-2-thia-5-azabicyclo[2.2.1]heptan-3-one (30.6 mg) in tetrahydrofuran (1 ml) was added 4-methylpiperazine (15.8 mg). The mixture was stirred for 33 hours at room temperature. After the reaction was over, the mixture was diluted with ethyl acetate (2 ml). Distillation of the solvent gave oily 1-[(2S,4S)-1-allyloxycarbonyl-4-mercapto-2-pyrrolidinecarbonyl]-4-methylpiperazine.
