White to Off White Low Melting Solid | [Uses]
2,4-Dichloro-5-methylpyrimidine, is used in the synthesis of (2-chloro-6-methyl-pyrimidin-4-yl)-(2,3-dihydro-benzothiazol-6-yl)-amine. It can react with piperidineto produce 2-chloro-5-methyl-4-piperidin-1-yl-pyrimidine. This reaction will need solvent dioxane. |
