1,1'-Thiocarbonyldiimidazole → HCID 178515269, compound

Participants

Reaction Steps

Compound 102 (2.0 g, 7.9 mmol) was then suspended in 80 ml of tetrahydrofuran, and 2.3 g (13 mmol) of thiocarbonyldiimidazole was added to the suspension. The mixture was heated to reflux for 2 hours. The solvent was distilled off under reduced pressure, and the residue was triturated with ethanol. The formed crystals were taken by filtration. Recrystallization from DMF gave 1.1 g (yield 47%) of Compound 20 as colorless crystals.
