Analyzing the synthesis route of 2-Hydroxy-5-iodo-3-(trifluoromethyl)pyridine

The synthetic route of 887707-23-5 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. 887707-23-5, name is 2-Hydroxy-5-iodo-3-(trifluoromethyl)pyridine, the common compound, a new synthetic route is introduced below. Product Details of 887707-23-5

A mixture of compound 12a2 (115 7 g, 400 mmol) and PhPOCI2 (668.6 g, 343 mmol) under N2 is stirred at 136C overnight, then cooled to room temperature and added slowly to 3 L of crushed ice. The aqueous mixture is adjusted to pH 6 and filtered. The aqueous filtrate is extracted with DCM (3 L) then the organic phase is washed with saturated NaHCO3 and brine, dried over Na2SO4, filtered and concentrated to provide chloropyridine 12a3.

The synthetic route of 887707-23-5 has been constantly updated, and we look forward to future research findings.
