Sodium Nitrate → HCID 68528728, compound

Participants

Reaction Steps

To a solution of [4-(5-aminopyridin-2-yloxy)phenyl](4-benzylpiperazin-1-yl)methanone (0.73 g, 1.88 mmol) in concentrated sulfuric acid (0.38 mL)-water (1.1 mL) were added dropwise a solution of sodium nitrate (0.13 g, 1.88 mmol) in water (0.6 mL) under ice cooling. The reaction mixture was stirred for 10 minutes. This reaction mixture was added to a solution of 3,4-dichlorobenzenethiol (0.24 mL, 1.88 mmol) in 2 N aqueous sodium hydroxide (2 mL) under cooling with ice. Water was added to the resulting reaction solution, and extracted with dichloromethane. The dichloromethane layer was dried over anhydrous magnesium sulfate, and evaporated. The residue was purified by silica gel chromatography (dichloromethane:methanol=80:1), to thereby yield 0.1 g of the title compound.
