1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 58902261, compound

Participants

Reaction Steps

To a solution of the hydrochloride salt of 7-[(2-aminopyridin-4-yl)oxy]-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid (1.99 g), tert-butyl [3-amino-5-(trifluoromethyl)-benzyl]carbamate (1.98 g, 6.82 mmol), and DMAP (0.834 g, 6.82 mmol) in DMF (60 mL) was added EDCI (1.31 g, 6.82 mmol). The reaction mixture was allowed to stir at rt overnight under an atmosphere of nitrogen. The reaction mixture was diluted with water and extracted with EtOAc. The organic solutions were combined, washed with water and brine, dried over Na2SO4, filtered, and concentrated. The residue was purified by column chromatography to give tert-butyl [3-[({7-[(2-aminopyridin-4-yl)oxy]-1,2,3,4-tetrahydronaphthalen-2-yl}carbonyl)-amino]-5-(trifluoromethyl)benzyl]carbamate (2.45 g, 71%). LCMS: (FA) ES+ 557.9, ES+ 554.6.
