Adding a certain compound to certain chemical reactions, such as: 1643-29-4, name is 3-(4-Iodophenyl)propanoic acid, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 1643-29-4, Formula: C9H9IO2
lntermediate-2; Methyl 3-(4-iodophenyl)propanoate.; Methanol (5 ml.) under nitrogen at O0C was added AcCI (0.4 ml_, 5.63 mmol). The reaction was stirred for 10 min before slow addition of 3-(4-iodophenyl)propanoic acid (498 mg, 1.80 mmol). The reaction was stirred for additional VA hour at room temperature, before the mixture was concentrated under vacuum, re-dissolved in MeOH and concentrated to give 512 mg (98%) of a pure white solid. Rf: 0.39 (EtOAc:hexanes, 1 :4); 1HNMR (CDCI3) delta 7.61-7.59 (m, 2H), 6.97- 6.94 (m, 2H), 3.66 (s, 3H), 2.92-2.87 (t, 2H, J = 7.5 Hz), 2.63-2.58 (t, 2H, J = 7.5 Hz); 13CNMR (CDCI3) delta 173.0, 140.1 , 137.5, 130.4, 91.4, 51.7, 35.4, 30.4; EI-MS m/z 290.0 (MH+).
