Versuchsvorschrift

A solution of 2,3-diamino-5-chlorobenzamide (0.75 g), tert-butyl 4-(4-carboxyphenyl)-piperidine-1-carboxylate (0.17 g), 1-hydroxybenzotriazole (HOBT, 0.22 g), benzotriazol-1-yl-oxytripyrrolidinophosphonium hexafluorophosphate (PyBOP, 0.85 g) and diisopropylethylamine (DIPEA, 0.85 mL) in DMF (5 mL) was stirred for 18 hours and concentrated. The concentrate was flash chromatographed on silica gel with 10% methanol/dichloromethane.
