Reaction Steps

To a solution of 1-Amino-2-(isopropylsulphonyl)benzene (350 mg, 1.6 mmol) in 4 mL of N,N-Dimethyl formamide at 0 degree, is added Sodium hydride (100 mg) and the reaction mixture is allowed to stirred at 0 degree for 20 minutes. 3,5-dichloropyridazine (1.6 mmol) is added and the reaction mixture is warmed to room temperature. The reaction mixture is stirred at room temperature until formation of the desired compound. The reaction mixture is quenched with water and extracted with Ethyl acetate. The combined Ethyl acetate layers are dried over Sodium Sulfate and solvent is removed under reduced pressure. The residue can be purified by Prep-HPLC.
