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.
