Reaction Steps

N-(2-Aminophenyl)-2-(2-anilino-4-oxo-4,5-dihydro-1,3-thiazol-5-yl)acetic acid, prepared using method 2 above, (30 mg, 1 eq) was dissolved in a mixture of DCM/DMF (2 mL/2 mL) and O-phenylendiamine (15 mg, 1.1 eq), and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (EDC, 30 mg, 1.3 eq) were then added sequentially. The reaction mixture was stirred 40° C. for 2 h.Separated between DCM and H2O, the organic layer concentrated to give a crude orange brown oil used directly in the next step: HPLC 43%, RT=0.93 min (System B, 2-95% MeCN over 2 min); MS [M+H]+ m/z=341.
