Trifluoroacetic acid → HCID 20251751, compound

Participants

Reaction Steps

(E)-7-Phenyl-7-(3-pyridyl)-6-hepten-1-ol (2.0 g, 7.4 mmoles) was dissolved in methylene chloride (20 ml), and sodium cyanate (0.50 g, 7.7 mmoles) and trifluoroacetic acid (5 ml) were added. The mixture was stirred at room temperature for 20 hours and concentrated under reduced pressure. The residue was shaken with potassium carbonate (1 g), water (20 ml) and methylene chloride (50 ml), and the organic layer was separated, washed with water, dried and concentrated. Recrystallization of the residue from isopropyl ether gave 1-carbamoyloxy-(E)-7-(3-pyridyl)-6-heptene (1.82 g, 79%) (Compound Id-23).
