Triethylamine → Pyrimidine-5-carboxylic acid{1-[2-chloro-4-(2-chloro-phenoxy)-benzyl-carbamoyl]-cyclopropyl}-amide

85 mg (0.84 mmol) of triethylamine, 130 mg (0.40 mmol) of TBTU and 100 mg (0.37 mmol) of 2-chloro-4-(2-chloro-phenoxy)-benzylamine were added to a solution of 80 mg (0.38 mmol) of 1-[(pyrimidin-5-carbonyl)-amino]-cyclopropanecarboxylic acid (from 1 b) in 30 mL tetrahydrofuran and 5 mL DMF and the mixture was stirred overnight at ambient temperature. Then the mixture was evaporated to dryness and the residue was combined with 2 M potassium carbonate solution. It was extracted with ethyl acetate and the organic phase was washed with water and saturated sodium chloride solution, dried and evaporated down. The crude product thus obtained was purified by reversed-phase chromatography. The fractions were evaporated down to the aqueous phase, made basic with ammonia and extracted with ethyl acetate. The organic phase was washed with saturated sodium chloride solution, dried and evaporated down. The residue was evaporated out with ether and dried.
