HCID 11357934(3s,6r,7As)-6-amino-5-oxohexahydropyrrolizine-3-carbonitrile trifluoroacetate

実験手順

80 mg of tert-butyl ((2R,5S,7aS)-5-cyano-3-oxohexahydropyrrolizin-2-yl)carbamate were C reacted with 10% thioanisole in 1 ml of trifluoroacetic acid for 30 min. The solvents were then removed in vacuo, and the residue was stirred with diusopropyl ether.
