Synthetic Route of 3196-15-4, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 3196-15-4 as follows.
[1074] Step 4: methyl 2-(6-(hydroxymethyl)-2-((4-methylbenzoyl)imino)benzo[d]thiazol-3(2H)-yl)butanoate[1075] To a solution of N-(6-(hydroxymethyl)benzo[d]thiazol-2(3H)-ylidene)-4-methylbenzamide (500 mg, 1.676 mmol) prepared in Step 3 in N,N-dimethylformamide (10 mL) were added potassium carbonate (695 mg, 5.028 mmol) and methyl 2-bromobutyrate (289 uL, 2.514 mmol). The reaction mixture was stirred at 50 ? overnight. .The reaction mixture was quenched with water and then extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered, and then evaporated. Isopropyl ether was added to the resulting residue and then filtered. The resulting solid was dried under reduced pressure to give 470 mg of the titled compound as a white solid (Yield: 70%).[1076] 1H NMR (CDCl3, 400 MHz); 8.19 (d, 2H), 7.76 (s, 1H), 7.44 (d, 1H), 7.26 (m, 3H), 5.60 (brs, 1H), 4.79 (s, 2H), 3.65 (s, 3H), 2.51 (m, 2H), 2.42 (s, 3H), 1.97 (s, 1H), 1.57 (s, 2H), 0.89 (t, 3H).
According to the analysis of related databases, 3196-15-4, the application of this compound in the production field has become more and more popular.
