Reaction Steps

A solution of 2-(6-pivalamidopyridazin-3-yl)acetate (740 mg, 2.52 mmol) in 6 N hydrochloric acid (24 mL) was heated to 105° C. for 12 h, then cooled and concentrated in vacuo. The resulting crude residue was redissolved in methanol (10 mL) and treated dropwise with a 2 N solution of trimethylsilyldiazomethane in diethylether (2.52 mL, 5.04 mmol). After 1 h, the mixture was diluted with water and extracted with EtOAc. The organic layer was washed with water and brine, dried (sodium sulfate), filtered and concentrated to provide title compound. LC-MS (IE, m/z): 168 [M+1]+.
