Vorschrift

1-(1-(4-chlorobenzyl)-1H-indole-2-carbonyl)piperidine-4-carboxylic acid (100 mg, 0.252 mmol), N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (72.5 mg, 0.378 mmol), and 1H-benzo[d][1,2,3]triazol-1-ol (51.1 mg, 0.378 mmol) were dissolved in 2.0 mL of DCM and stirred for 10 minutes before the addition of a 2-(4-isopropylphenyl)ethanamine, HCl (75 mg, 0.378 mmol) and N-ethyl-N-isopropylpropan-2-amine (0.132 mL, 0.756 mmol) as a 1.0 mL DCM solution. The reaction was allowed to stir overnight. The reaction was diluted with water and ethyl acetate. The organic layer was washed with 1N HCl, saturated sodium bicarbonate solution, and finally saturated sodium chloride solution. The organic layer was dried over magnesium sulfate, filtered and concentrated. The crude material purified using silica gel chromatography 0-60% ethyl acetate/hexanes.
