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. 59237-53-5, name is Methyl 6-chloro-5-nitronicotinate, the common compound, a new synthetic route is introduced below. COA of Formula: C7H5ClN2O4
11231] To a solution of 643-1 (1.5 g, 6.9 mmol) in DMF (20 mL) was added 2- benzyloxyl ethanol (6.3 g, 41 mmol) at 25 °C. The solution wras stirred for 6 h and then poured into 0 (20 mL). The mixture was extracted with EA (2 x 40 mL). The combined organic phase was washed with brine, dried over anhydrous Na^SC^ and concentrated under reduced pressure. The residue was purified by column chromatography using 5-10percent EA in PE as the eluent to give a mixture of 643-2 and 643-2 A ( 1 .50 g).
The synthetic route of 59237-53-5 has been constantly updated, and we look forward to future research findings.
