Reaction Steps

A mixture of p-TSA (117 mg, 0.618 mmol), 2,5-hexanedione (4.36 mL, 37.1 mmol) and 3-amino-6-chloropyridazine (4.00 g, 30.9 mmol) in toluene (150 mL) was heated at 140° C. for 5 h in a round bottom flask equipped with a condenser and Dean-Stark apparatus. The reaction mixture was cooled to rt and charcoal was added. The mixture was filtered through CELITE and concentrated in vacuo to afford the title compound i-6a. m/z (ES) 208 (MH)+.
