Triethylamine → HCID 178522952, compound

Participants

Reaction Steps

To a mixture of 4,5,6,7-tetrahydroimidazo[4,5-c]pyridine dihydrochloride (0.50 g, 2.55 mmol), ethanol (10 mL) and triethylamine (1.10 mL, 7.89 mmol), 2,4-dichlorobenzyl isocyanate (0.52 g, 2.57 mmol) was added. The resulting mixture was stirred at room temperature for 16 h and then concentrated under reduced pressure. The residue was distributed between water (20 mL) and ethyl acetate (75 mL). The organic phase was washed with water (10 mL) and brine (10 mL), dried (MgSO4) and concentrated under reduced pressure. The residue was triturated in diethylether (50 mL) and the crude product was filtered off. Recrystallization from acetone (25 mL) gave 0.30 g (37%) of the title urea as a colourless solid.
