Versuchsvorschrift

In a RBF was charged 5-((2-cyclopentylethyl)carbamoyl)-2-methylbenzoic acid (0.25 g, 0.91 mmol), DCM (3 ml), n,n-diisopropylethylamine (0.6 ml, 3.5 mmol), HOBt (0.14 g, 1.0 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.21 g, 1.1 mmol), and 2,5-diaminopyridine (0.1 g, 0.91 mmol) in that order. This mixture was stirred at RT under N2 for 18 h. The reaction was partitioned between DCM (30 ml) and brine (20 mL). The precipitate formed was collected, washed with water, dried in a vacuum oven overnight to give N3-(6-aminopyridin-3-yl)-N1-(2-cyclopentylethyl)-4-methylisophthalamide as a purple solid. MS (ESI, pos. ion) m/z: 367.2 (M+1).
