Sources of common compounds: 14394-70-8

The synthetic route of 14394-70-8 has been constantly updated, and we look forward to future research findings.

In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 14394-70-8, name is 2-Chloro-5-methylpyrimidin-4-amine, the common compound, a new synthetic route is introduced below. Application In Synthesis of 2-Chloro-5-methylpyrimidin-4-amine

[0228] A mixture of 2-chloro-5-memyl-pyrimidin-4-ylamine (0.30 g, 2.1 mmol), A- bromo-l-chloro-2-trifluoromethyl-benzene (0.40 mL, 2.7 mmol), Pd2(dba)3 (0.10 g, 0.11 mmol), Xantphos (0.13 g, 0.22 mmol) and cesium carbonate (1.5 g, 4.6 mmol) in. dioxane/DMF (6/1, 7 mL) was sealed in a microwave reaction tube and irradiated with microwave at 160 C for 15 min. After cooling to room temperature, the cap was removed and the resulting mixture filtered and the filtered solid washed with DCM. The filtrate was concentrated and the residue purified by flash chromatography on silica gel (hexanes to 50% EtOAc/hexanes) to afford the title compound (0.65 g, 96%) as a white solid. MS (ES+): m/z 322 (MH-H)+.

The synthetic route of 14394-70-8 has been constantly updated, and we look forward to future research findings.
