These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 108078-14-4, its application will become more common.
Some common heterocyclic compound, 108078-14-4, name is 2-Iodo-3-methylbenzoic acid, molecular formula is C8H7IO2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Safety of 2-Iodo-3-methylbenzoic acid
EXAMPLE 156; 136 5,6-Difluoro-2-d-iodo-3-methyl-benzoylamino)-indan-2-carboxylic acid ethyl ester (156):To a solution of 2-iodo-3-methyl-benzoic acid (1.5Og, 5.75mmol), 2-amino-5,6-difluoro- indan-2-carboxylic acid ethyl ester (1.39g, 5.75mmol), HATU (2.63g, 6.90mmol) in anhydrous DMF (6mL) is added DIPEA (1.14mL, 6.90mmol). The resulting solution is stirred at RT overnight. After the removal of DMF in vacuo, the residue is dissolved in EtOAc (20OmL) and washed with water (I x 2OmL) and brine (2 x 2OmL). The organic layer is dried over anhydrous Na2SO4 and concentrated in vacuo. The residue is purified by flash column chromatography (40Og silica gel, gradient elution: 10%-80% EtOAc in heptane) to give a pure product (156) as white solid (2.32g, 83%).1H NMR (CDCl3, 300MHz): delta 1.29(t, 3H), 2.45(s, 3H), 3.48(d, 2H), 3.63(d, 2H), 4.27(q, 2H), 6.38 (s, IH), 7.04(t, 2H), 7.10-7.13(m, IH), 7.24-7.27(m, 2H) LC/MS (ES+) m/z = 486.02
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 108078-14-4, its application will become more common.
