Sodium Carbonate → 3,6-Dichloro-5-{[3-fluoro-5-(trifluoromethyl)phenyl]sulfanyl}-1,2,4-triazine

Participants

Reaction Steps

To a solution of 3,5,6-trichloro-1,2,4-triazine (3 mmol) in dry THF (30 mL) at −78° C. under nitrogen atmosphere is added 3-fluoro-5-(trifluoromethyl)benzenethiol (3 mmol) and sodium carbonate (3 mmol). The reaction is allowed to reach room temperature and is stirred at room temperature until formation of the desired compound. The solvent is evaporated. The residue is suspended in water and extracted with CH2Cl2. The dichloromethane solution is dried over MgSO4 and evaporated. The residue is chromatographed on a silica gel column.
