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 solution of 2-methylthiazole-5-carbaldehyde (1 g, 7.86 mmol) and ethyl 2-azidoacetate (30% in DCM, 15.8 ml_, 31 .5 mmol) was added dropwise to a solution of NaOEt (21 % in EtOH, 1 1 .7 ml_, 31 .5 mmol) and EtOH (40 ml.) at 0. After stirring for 1 hour at 0C, the temperature was allowed to come to RT and the stirring was continued for another hour. The mixture was quenched with a saturated solution of NH4CI and extracted with Et20. The organic extract was dried over Na2S04, filtered and evaporated. Purification by column chromatography on silica gel using cyclohexane and EtOAc (from 0% to 30%) provided the title compound as brown solid. 1 H NMR (400 MHz, DMSO-d6) d (ppm) 8.07 (d, 1 H), 7.27 (d, 1 H), 4.31 (q, 2H), 2.69 (s, 3H), 1 .32 (t, 3H). LC-MS: Rt = 1 .05 min; MS m/z [M+H]+ 239.1
1003-60-7, As the paragraph descriping shows that 1003-60-7 is playing an increasingly important role.
