With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3829-80-9,Methyl 2-amino-4-methylthiazole-5-carboxylate,as a common compound, the synthetic route is as follows.,3829-80-9

A mixture of bromoacetaldehyde diethyl acetal (29.3 mmol, 1.26eq) in water (200 mL) is treated dropwise with cone, hydrochloric acid (3.0 mL), stirred for 14h at RT and heated for additional 30 min at 800C. After cooling to RT NaHCO3 (37.9 mmol) is added carefully and the mixture is stirred for 2h and treated with 2-Amino-4-methyl-thiazole-5- carboxylic acid methyl ester (23.2 mmol, l.OOeq). After Ih dioxane (130 mL) is added and the mixture is stirred at RT for 30 min and at 1000C for 48h. The organic solvents are removed in vacuo and the mixture is extracted several times with DCM and chloroform. The combined organic layers are dried over Na2SO4 and concentrated in vacuo to give the desired ester which is used without further purification. LC-MS: tR = 0.55 min; [M+H]+ = 197.0.

As the paragraph descriping shows that 3829-80-9 is playing an increasingly important role.

3829-80-9, Methyl 2-amino-4-methylthiazole-5-carboxylate is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

PREPARATION 9 To a mixture of methyl 2-amino-4-methylthiazole-5-carboxylate (3.72 g) and pyridine (25 ml) was added mesyl chloride (1.6 ml) over the period of 5 minutes under cooling with stirring, and the mixture was stirred for 1 hour at ambient temperature and for 3 hours for 40 C. After the reaction mixture was concentrated, ethyl acetate (50 ml) and tetrahydrofuran (20 ml) were added to the residue and the mixture was adjusted to pH 3 with diluted hydrochloric acid. The separated organic layer was washed with brine, dried over magnesium sulfate and concentrated. The residue was pulverised with diethyl ether to give methyl 2-mesylamino-4-methylthiazole-5-carboxylate (3.5 g). mp: 216-218 C.
