Generally, it requires fewer steps, and cheap raw materials. 1643-29-4, name is 3-(4-Iodophenyl)propanoic acid, A new synthetic method of this compound is introduced below., Computed Properties of C9H9IO2

3-(4′-Iodophenyl)propanoic acid (10 mmol, 2.76 g, 1.0 eq.) and N-hydroxysuccinimide (15 mmol, 1.73 g, 1.5 eq) were dissolved in anhydrous CH2Cl2 (40 mL). The mixture was cooled to 0 C., and N,N’-dicyclohexylcarbodiimide (DCC, 15 mmol, 3.09 g, 1.5 eq) dissolved in 20 mL CH2Cl2 was added drop-wise slowly. The mixture was stirred overnight at room temperature. The N,N’-dicyclohexylurea was filtered out, the residue was washed with CH2Cl2, and the filtrate was evaporated to dryness purified by column chromatography and recrystallization with iso-propanol or toluene/hexane to afford succinimide as white solid (3.50 g, 94%). 1HNMR (400 MHz, CD3CN) delta 7.66 (d, J=8.4 Hz, 2H), 7.08 (d, J=8.4 Hz, 2H), 2.95 (A2B2, t, 4H), 2.75 (s, 4H). 13CNMR (100 MHz, CD3CN) delta 168.4, 166.7, 138.1, 135.9, 129.2, 89.5, 30.1, 27.8, 23.8; HRMS (ESI) Calcd for C13H12NO4INa (M+Na)+: 395.9709; Found: 395.9706.
