Reaction Steps

In analogy to compound 1.1, a solution of 0.34 g (1.49 mmol) of 5-bromo-2,4-dichloropyrimidine in 5 ml of acetonitrile is reacted with 0.1 ml (1.61 mmol) of ethanolamine in the presence of 0.25 ml (1.81 mmol) of triethylamine. Recrystallization from hexane/ethyl acetate 7/3 results in 0.28 g (74% of theory) of the product.
