119778-44-8, 4-Ethyl-2-methylthiazole-5-carboxylic acid is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
EXAMPLE 7 In a similar apparatus to Example 1, 8.6 g (0.05 mole) of 2-methyl-4-ethylthiazole-5carboxylic acid were suspended in 200 ml of toluene. Under heating and reflux, phosgene was blown at a rate of 340 ml/hr for 12 hours (0.18 mole). After completion of the reaction, the reaction mixture was filtered and the filtrate was concentrated to obtain 9.2 g of 2-methyl-4-ethylthiazole-5-carboxylic acid chloride. Its purity and yield were 96.0% and 96.6%, respectively. NMR (deltaCDCl 3/TMS, ppm): 1.25(3H,t,J=8Hz), 2.46(3H,s), 3.06(2H,q,J=8Hz)., 119778-44-8
As the paragraph descriping shows that 119778-44-8 is playing an increasingly important role.
