A new synthetic route of 105806-13-1

The synthetic route of 105806-13-1 has been constantly updated, and we look forward to future research findings.

Reference of 105806-13-1 , The common heterocyclic compound, 105806-13-1, name is 4,6-Dichloro-5-fluoro-2-methylpyrimidine, molecular formula is C5H3Cl2FN2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

Part C: A mixture of 4,6-dichloro-5-fluoro-2-methylpyrimidine (1.55 g, 8.56 mmol), ammonium hydroxide (35%, 10.0 mL, 257 mmol), and MeOH (1.00 mL) was heated, in a sealed tube, at 70 0C for 2h. The reaction mixture was cooled to RT, and a precipitate was formed. The reaction mixture was diluted with water (ca. 10 mL) and was stirred 30 min. The solids were collected by suction filtration, washed with water and air-dried to give 4-amino-6-chloro-5-fluoro-2-methylpyrimidine (845 mg, 61%) as a tan solid. LCMS (m/z): 162,164 (M+H)+

The synthetic route of 105806-13-1 has been constantly updated, and we look forward to future research findings.
