Application of 1780-26-3, 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 1780-26-3, name is 2-Methyl-4,6-dichloropyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
I) Synthesis of N-(6-chloro-2-methylpyrimidin-4-yl)thiazol-2-amine To a cool (0 C.), stirring suspension of 2-aminothiazole (3.05 g, 0.0305 mol), 4,6-dichloro-2-methylpyrimidine (5.84 g, 0.0358 mol) in THF (50 mL) was added dropwise over 10 minutes via addition funnel a solution of t-BuOK (40 mL, 30% wt in THF, 0.1069 mol). The reaction was allowed to slowly warm to room temperature overnight. To the reaction was added water (40 mL) and the resulting clear solution was extracted with chloroform and then chloroform/methanol (4:1). The combined extracts were concentrated to near dryness to give a precipitate. The solid was collected by filtration to give the title material (3.559 g) as a solid. The filtrate was concentrated to dryness and the resulting solid was dissolved in boiling methanol and allowed to precipitate overnight aided with the addition of some water. The solid was collected by filtration, washed with water and air dried to give the title material (1.451 g) as a solid. The aqueous layer from the extraction was acidified with 10% HCl and a precipitate was formed. The solid was collected by filtration, washed with water to give the title material (1.559 g) as a solid. The solids were combined to give the title material (6.569 g, 95%). 1H NMR (400 MHz, DMSO-d6) delta (ppm): 2.53 (3H, s), 6.90 (1H, s), 7.21 (1H, d, J=3.5 Hz), 7.46 (1H, d, J=3.5 Hz), 11.87 (1H, s). LC/MS (M+H)+: 227, 229. HPLC ret. time (Condition E): 1.427 min.
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 1780-26-3, 2-Methyl-4,6-dichloropyrimidine.
