Procedure

To a solution of 5-iodo-isophthalic acid monomethyl ester (3.00 g, 9.8 mmol) in N,N-Dimethylformamide (80 ml) was added dimethyl amine (2M solution in Tetrahydrofuran, 9.8 m, 79.61 mmol), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluoro-phosphate 3.72 g, 9.8 mmol), and finally di-iso-propyl ethyl amine (5.1 ml, 29.41 mmol), this mixture was stirred at room temperature over night. The solvent was stripped under reduced pressure and the crude purifies by silica gel chromatography to give afford 5-Iodo-N,N-dimethyl-isophthalamic acid methyl ester (2.46 g, 75%). MS: m/z 333.1 (M+H+).
