Versuchsvorschrift
2 g of MeSNa (28.5 mmol; 1 eq.) and 6.5 g of 5-bromo-2,4-dichloropyrimidine (28.5 mmol, 1 eq.) were stirred in 50 mL dry acetonitrile at rt for 24 h. Then the mixture was poured into water, extracted with DCM, dried (Na2SO4) and evaporated to dryness. The product was recrystallized from hexane to yield 4 g of Intermediate 12 (70% yield).
