Reaction Steps

In analogy to example 12c), by heating (E)-2-[2-(2,4-dimethoxy-phenyl)-vinyl]-6-methyl-pyrimidin-4-ol (0.33 g, 1.22 mmol) in POCl3 (2.24 ml, 24.5 mmol) at 130° C. for 4.5 h there was obtained 4-chloro-2-[2-(2,4-dimethoxy-phenyl)-vinyl]-6-methyl-pyrimidine (0.21 g, 60%) as a light yellow solid. EI mass spectrum, m/e: 290 (M calculated for C15H15ClN2O2: 290).
