Reaction Steps

40 mg (0.92 mmol) sodium hydride (55%, suspension in mineral oil) were added to 0.10 g (0.68 mmol) 2-hydroxyquinoxaline in 1.5 mL DMF and the mixture was stirred for 15 min. Then 0.11 g (0.69 mmol) 4,6-dichloropyrimidine were added and the mixture was stirred overnight at RT. The reaction mixture was purified by preparative HPLC-MS. The product-containing fractions were combined, the acetonitrile was eliminated i.vac., and the precipitated product was suction filtered and dried.
