4-(Trifluoromethoxy)benzoic acid → 4-{3-Methoxy-1-[3-(4-trifluoromethoxy-benzoylamino)-phenyl]-propylamino}-quinazoline-8-carboxylic acid amide

Participants

Reaction Steps

A mixture of 4-{[1-(3-aminophenyl)-3-methoxypropyl]amino}quinazoline-8-carboxamide (50.00 mg; 0.14 mmol; 1.00 eq.), N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (30 mg; 0.16 mmol; 1.10 eq.) and 1H-1,2,3-benzotriazol-1-ol (22 mg; 0.16 mmol; 1.10 eq.) in dry DMF (1 mL) were added 4-(trifluoromethoxy)benzoic acid (33 mg; 0.16 mmol; 1.10 eq.) and N-ethyl-N-isopropylpropan-2-amine (0.08 ml; 0.43 mmol; 3.00 eq.). The mixture was stirred overnight. After concentration, the crude was purified by reverse phase HPLC to obtain 26 mg of the title product in 34% yield.
