YieldReaction ConditionsOperation in experiment
With sodium carbonate In 1,2-dimethoxyethane for 1h; Reflux; 2 A suspension of 2-Amino-5-bromo-N-methoxy-N-methyl-nicotinamide (0.2 g, 0.77 mmol), N-cyclopropyl 3-boronobenzenesulfonamide (0.2 g, 0.84 mmol), Pd(dppf)Cl2.DCM (0.063 g, 0.077 mmol) in 2M Na2CO3 (1 ml) and DME (3 ml) is heated at reflux for 1 hour. The crude reaction mixture is subjected to column chromatography (Isolute C18, 0-100% MeCN in water -0.1% TFA). All the acetonitrile is removed in vacuo, and the aqueous solution remaining is adjusted to basic pH using NaHCO3. The product is extracted into DCM, and dried (MgSO4). Concentration and drying in vacuo at 40° C. yields the title compound. [M+H]+ 726
