Participants

Reaction Steps

Into 20 ml og tetrahydrofuran was dissolved 2 g of 2-butyryl-5-[4-(ethylthio)carbonylphenyl]-3-hydroxy-2-cyclohexen-1-one and to the solution was added 0.8 g of allyloxyamine. The mixture was kept for 15 hours at room temperature and the solvent was distilled off from it under reduced pressure. Then, the residue was recrystallized with mixture of benzene-ligroin and 0.8 g of colorless objective crystals having a melting point of 72°-75° C. was obtained.
