Embodiment 1
[0041] Example 1 Synthesis of N-(2-chlorophenethyl)-2-methyl-thiazole-4-carboxamide
[0042] The reaction formula is as follows:
[0043] The synthesis steps are as follows:
[0044] (1) Dissolve 2-methylthiazole-4-carboxylic acid (1mmol) in 5mL of dichloromethane solution at 0°C, slowly add oxalyl chloride (0.17mL) and N,N-dimethylformaldehyde Amide (1 drop), add and react at room temperature for 1 hour, and after the reaction is completed, the solvent is distilled off under reduced pressure to obtain a residue;
[0045] (2) Dissolve the residue in 2 mL of dichloromethane, add 2-(2-chlorophenyl)ethylamine (1 mmol), dichloromethane (5 mL) and triethylamine (0.16 mL) into a mixed solution, and stir at room temperature 24h. After the completion of the reaction was confirmed by TLC analysis, the solvent was distilled off under reduced pressure, and the residue was purified by flash column chromatography to obtain the target compound as a colorless oil with a yield of 84.3%.
