実験手順
2,4-bis(methyloxy)-5-(2-methyl-1,3-thiazol-4-yl)pyrimidine (Prep19, 290 mg, 1.222 mmol) was suspended in HCl 4M in 1,4-dioxane (10 ml). The reaction mixture was heated at 90° for 1 h and left at room temperature overnight. The solvent was then removed in vacuo to give the title compound as a solid (287 mg).
