Reaction Steps

For amide formation, 3-(oxazolo[4,5-b]pyridin-2-yl)benzoic acid (30 mg, 0.125 mmol) was dissolved in 2 mL of DMF along with 3,4,5-trimethoxyaniline (23 mg, 1 eq) and 71 mg of HATU (1.5 eq). After 45 microliters of DIEA (2 eq) were added, the reaction mixture was stirred at room temperature for 18 hrs. It was then diluted with ethyl acetate and washed with water and concentrated. The resulting residue was purified by chromatography using a 9:1 mixture of CH2Cl2 to MeOH to afford 3-(oxazolo[4,5-b]pyridin-2-yl)-N-(3,4,5-trimethoxyphenyl)benzamide. (MS, M++H=406).
