Reference of 3475-21-6, 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 3475-21-6, name is 4-Methyl-2-phenylpyridine. This compound has unique chemical properties. The synthetic route is as follows.
2-phenyl-4-methylpyridine (6 g, 35.4 mmol) and SeO2 (24 g, 216 mmol) were refluxed in pyridine (100 ml) overnight under argon. The mixture was then filtered through celite while hot. The Celite filter cake was rinsed with pyridine (3×50 ml) and the resulting filtrate evaporated to dryness. The solid thus obtained was triturated in water (200 ml) and filtered off. The resulting brown solid was suspended in a mixture of water (150 ml) and MeOH (200 ml) and made basic by addition of an aqueous NaOH solution. The mixture was then filtered over Celite to removed some insoluble materials. The filtrate was then acidified with concentrated HCl. MeOH was evaporated and the formed precipitate was filtered, washed with water, then small portions Of Et2O (3×20 ml) and finally dried to afford 5.9 g (84%) of the titled compound as a slightly brown solid.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 3475-21-6, 4-Methyl-2-phenylpyridine.
