Sodium Azide → HCID 21471655, compound

Participants

Reaction Steps

A mixture of 0.15 g of 1,3-dihydro-1-{1-[1-(6-chloro-2-pyrazinecarbonyl)piperidin-4-yl]piperidin-4-yl}-2H-benzimidazol-2-one, 0.26 g of sodium azide and 5 mL of anhydrous N,N-dimethylformamide was stirred for 24 h, then concentrated to dryness under reduced pressure. The residue was partitioned between 50 mL of chloroform and 5 mL of saturated sodium carbonate and the organic extracts dried over MgSO4. Removal of solvents under reduced pressure and drying under vacuum gave 0.16 g of crude 1,3-dihydro-1-{1-[1-(6-azido-2-pyrazinecarbonyl)piperidin-4-yl]piperidin-4-yl}-2H-benzimidazol-2-one.
