A suspension of 3,6-dichloropyridazine-4-carboxylic acid (5.5 g, 28.5 mmol) in DCM (50.0 ml) and MeOH (10 ml) was added trimethylsilyldiazomethane (2 M in hexane, 15 ml, 30.0 mmol) slowly at 0 C. It became a clear solution after the addition. It was stirred for 30 min and was added another 15 mL of trimethylsilyldiazomethane and stirred for 30 min. It was quenched with (0170) 2 mL of acetic acid, concentrated and purified by ISCO (80g, 0-40% ethyl acetate in hexane) to give the title compound. MS (ESI): m/z 206 (M+H) +, 51149-08-7
