Reaction Steps

2-Amino-5-iodobenzoic acid (5.0 g, 19 mmol) was dissolved in dichloromethane (100 mL). O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (7.9 g, 21 mmol) and triethyl amine (2.1 g, 21 mmol) were added with magnetic stirring. After 5 min., dimethyl amine (2 N in THF, 19 mL, 38 mmol) was added and the resulting solution was stirred overnight. The reaction solution was washed with aqueous saturated sodium chloride and concentrated. The residue was purified by flash chromatography on silica gel using a gradient of methanol in dichloromethane to afford 2-amino-5-iodo-N,N-dimethyl-benzamide (5.4 g, 98% yield) as yellow solids. MS: m/z 291 (M+H+).
