Reaktionsschritte

2-(2-Bromophenoxy)pyrimidin-5-amine (3.01 g, 11.3 mmol), 1-chloro-4-phenylphthalazine (2.72 g, 11.3 mmol), and butan-2-ol (56.6 ml, 11.3 mmol) were placed in a sealed tube. The reaction vessel was sealed and mixture heated to 120° C. After 1.5 h, LCMS showed mainly product as [M+H]+=470 and a small amount of bromo starting material. 200 mg of phthalazine was added. After another 3.5 h, the reaction was cooled to RT. Hexane was added to allow a yellow solids to precipitate. The yellow solids were filtered and recrystallized with DCM and hexanes. The resulting dark brown solids were dried under vacuum overnight, affording the product, N-(2-(2-bromophenoxy)pyrimidin-5-yl)-4-phenylphthalazin-1-amine.
