    • Equivalent amount of substituted salicylic acid and aniline were mixed in Ph-Cl. Phosphorus trichloride (0.5 equiv) was added. The mixture was then irradiated in MW reactor MicroSynth (450W) for 20 min to reflux. Then, the reaction mixture was cooled, and the crude product collected by filtration, followed by recrystallization from acetone to obtain pure product

    • General literature procedure (3b) for compound 3: N -CBZ or N -BOC protected 2-amino acid 2 (10 mmol) and substituted salicylanilide 1 (10 mmol) were dissolved in dry DMF (45 mL). The solution was cooled to -15 °C and N, N′- dicyclohexylcarbodiimide (DCC, 11 mmol) was added in three portions during 1 h. The mixture was stirred for 3 h at the same temperature and stored at +4 °C for 20 h. The precipitate of N, N′- dicyclohexylurea was removed by filtration, and the solvent was evaporated in vacuo. The crude product 3 was purified by crystallization from ethyl acetate-hexane.
