A new synthetic route of 2-(Chloromethyl)-5-methylpyridine hydrochloride

The synthetic route of 71670-70-7 has been constantly updated, and we look forward to future research findings.

Adding a certain compound to certain chemical reactions, such as: 71670-70-7, 2-(Chloromethyl)-5-methylpyridine hydrochloride, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, HPLC of Formula: C7H9Cl2N, blongs to pyridine-derivatives compound. HPLC of Formula: C7H9Cl2N

To 3,5-difluoro-4-nitrophenol (7.44 g, 42.5 mmol), Cs2CO3 (27.7 g, 84.9 mmol), and 2-(chloromethyl)-5-methylpyridine hydrochloride (7.6 g, 42.5 mmol) was added DMF (281 mL) and the reaction was stirred at 75 Celsius for 18 hours. The reaction was allowed to cool to room temperature before being poured into sat. NaHCO3. The aqueous phase was extracted three times with EtOAc, and the combined organic layers were washed four times with brine, dried (Na2SO4), filtered, and concentrated. The crude material was purified via FCC to afford the title compound. MS (ESI): mass calcd. for C13H10F2N2O3, 280.1; m/z found, 281.0 [M+H]+.

The synthetic route of 71670-70-7 has been constantly updated, and we look forward to future research findings.
