With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2346-00-1,2-Methyl-4,5-dihydrothiazole,as a common compound, the synthetic route is as follows.
2-Methyl-2-thiazoline 7 (16.57g, 162.1 mmol, 1 eq.) was placed in a 250 ml flask, followed by dried THF (75.6 mL) and CH3I (23.26 g, 162.2 mmol, 1 equiv). The flask was wrapped with aluminum foil and the mixture was stirred for 18 h at room temperature. White crystals of product 14 were filtered, washed with dried THF and vacuum-dried. 20.57 g (84.6 mmol) of 14 was obtained, yield 52.2percent. Melting point, 1H and 13C NMR spectroscopy data, and IR spectroscopy data are available in ref. 3., 2346-00-1
As the paragraph descriping shows that 2346-00-1 is playing an increasingly important role.
