Participants

Reaction Steps

EDCI (6 mg, 0.033 mmol) and HOBt (5 mg, 0.033 mmol) were added to a solution of 7-(4-bromo-2-chlorophenylamino)-3-[(tert-butoxycarbonylmethylamino)-methyl]-8-chloroimidazo[1,2-a]pyridine-6-carboxylic acid (61) in dimethylacetamide (0.4 mL). The yellow solution was allowed to stir at room temperature for 0.5 hours after which time O-cyclopropylmethyl-hydroxylamine (6 mg, 0.066 mmol) and triethylamine (6 μL, 0.044 mmol) were added and the solution allowed to stir overnight. The reaction mixture was diluted with ethyl acetate, washed with water, saturated aqueous ammonium chloride, saturated aqueous potassium carbonate and brine. The organic phase was dried over NaSO4, filtered, concentrated in vacuo to provide the desired product as a yellow residue (11.5 mg, 85%). MS (APCI+) m/z 612, 614, 616 (M+; Cl, Br pattern) detected.
