The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 3993-78-0, name is 2-Amino-4-chloropyrimidine. This compound has unique chemical properties. The synthetic route is as follows. Safety of 2-Amino-4-chloropyrimidine
5-Methoxy-1H-pyrrolo[3,2-b]pyridine (201-20) (200 mg, 1.35 mmol, 1 eq), cesium carbonate (877.5 mg, 2.7 mmol, 2 eq) and 4-chloropyrimidin-2-amine (203-20) (261 mg, 2.025 mmol, 1.5 eq) were mixed in N-methylpyrrolidone (5 mL). The mixture was heated to 150C and stirred to react for 2 hours. After the reaction was completed, the temperature was lowered to room temperature, and the reaction mixture was quenched with water, filtered and the residue was washed with water, dried in vacuum to give a gray solid (300 mg, yield: 92.13%). LCMS (ESI): m/z 242[M + H]+.
With the rapid development of chemical substances, we look forward to future research findings about 3993-78-0.
