Reaction Steps

In analogy to example 12c), by heating (E)-3-[2-(4-hydroxy-6-methyl-pyrimidin-2-yl)-vinyl]-benzonitrile (1 g, 4.21 mmol) in POCl3 (7.7 ml, 84.3 mmol) at 130° C. for 4.5 h there was obtained (E)-3-[2-(4-chloro-6-methyl-pyrimidin-2-yl)-vinyl]-benzonitrile (1.07 g, 99%) as an orange solid. EI mass spectrum, m/e: 255 (M calculated for C14H10ClN3: 255).
