Participants

Reaction Steps

N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (259 mg, 1.350 mmol), 1-(1-(4-chlorobenzyl)-1H-indole-2-carbonyl)piperidine-4-carboxylic acid (428 mg, 1.080 mmol), and 1H-benzo[d][1,2,3]triazol-1-ol (182 mg, 1.350 mmol) were dissolved in 4.0 mL of DCM. The reaction was stirred at room temperature for ten minutes before Hunig's Base (0.236 ml, 1.350 mmol) and (1-methyl-1H-pyrazol-3-yl)methanamine (100 mg, 0.900 mmol) as a 1.0 mL DCM solution was added. The reaction was allowed to stir at room temperature overnight. The reaction was diluted with water and ethyl acetate. The organic layer was washed with water, saturated sodium bicarbonate (twice), and saturated sodium chloride. The organic phase was dried over magnesium sulfate, filtered and concentrated. The resulting material was triturated with ethyl acetate to obtain white solid as the product. 1H-NMR (400 MHz, DMSO-d6) 8.18, 7.66-7.51, 7.35, 7.22, 7.12, 6.73, 6.05, 5.49, 4.40, 4.18, 3.96, 3.77, 2.93, 2.41, 1.69, 1.44
