With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1003-60-7,2-Methylthiazole-5-carbaldehyde,as a common compound, the synthetic route is as follows.
(a) An aqueous solution of 2% sodium hydroxide (3 ml) was added to a solution of 2-methyl-thiazole-5-carboxaldehyde (2.5 g) in acetone (20 ml) and water (10 ml). The mixture was stirred for 24 hours at ambient temperature, diluted with water (150 ml) and extracted with chloroform (2*50 ml). The organic layer was washed with water then dried over anhydrous magnesium sulphate and filtered. Evaporation of the solvent gave 1-(2-methyl-5-thiazolyl)but-1-en-3-one as a low-melting point solid (1.4 g, 43%). Pmr spectrum (CDCl3; delta in ppm): 2.30 (3H,s); 2.72 (3H,s); 6.36 (1H,d); 7.56 (1H,d); 7.74 (1H,s).
1003-60-7, 1003-60-7 2-Methylthiazole-5-carbaldehyde 13934728, athiazole compound, is more and more widely used in various.
