Application of 939412-86-9, 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. 939412-86-9, name is (3-Chloropyrazin-2-yl)methanamine hydrochloride belongs to pyrazines compound, it is a common compound, a new synthetic route is introduced below.
A mixture of SM (1.4 g, crude, 7.8 mmol), (3-chloropyrazin-2-yl)methanamine hydrochloride (1.4 g, 7.8 mmol), HATU (2.7 mg, 7.8 mmol) and TEA (3.2 mg, 31.2 mmol) in DCM (30 mL) was stirred at 25C overnight. The mixture was quenched with H20 (60 mL) and it was extracted with DCM (25 mL X 3). The combined organic layers were dried over anhydrous sodium sulfate, filtered and concentrated to give a crude product. The crude product was purified by prep- TLC to give 1 (1.3 g, 50 %). LCMS: m/z = 309 [M+H]+.
The synthetic route of (3-Chloropyrazin-2-yl)methanamine hydrochloride has been constantly updated, and we look forward to future research findings.
