The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 71670-70-7, name is 2-(Chloromethyl)-5-methylpyridine hydrochloride. This compound has unique chemical properties. The synthetic route is as follows. Recommanded Product: 2-(Chloromethyl)-5-methylpyridine hydrochloride
EXAMPLE 7 Preparation of 2-methyl-6-[[(5-methyl-2-pyridyl)methyl]-thio]-5H-1,3-dioxolo(4,5-f)benzimidazole To 3.9 g of 2-methyl-5H-1,3-dioxolo-(4,5-f)benzimidazole-6-thiol, suspended in 60 ml of alcohol, were added dropwise while stirring 1.57 g of sodium hydroxide in 30 ml of water and, after 30 minutes, there were added 3.44 g of 5-methyl-2-chloromethylpyridine hydrochloride. The mixture was left to boil at reflux overnight, then evaporated and the residue was taken up in 500 ml of ethyl acetate. This was washed with 100 ml of sodium hydroxide, three times with 100 ml of water, dried over sodium sulfate and evaporated in vacuo. The crude product was recrystallized from ethyl acetate/petroleum ether (low boiling) and there were obtained 4.8 g (81.7% of theory) of 2-methyl-6-[[(5-methyl-2-pyridyl)methyl]-thio]-5H-1,3-dioxolo(4,5-f)benzimidazole of melting point 147-148 C.
With the rapid development of chemical substances, we look forward to future research findings about 71670-70-7.
