tert-butyl N-(4-aminobutyl)carbamate → HCID 67074087, compound

Participants

Reaction Steps

To a solution of 4-(4-(1-(ethoxycarbonyl)cyclopropylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzoic acid (100 mg) in DMF (5 mL) was added tert-butyl 4-aminobutylcarbamate (64.0 mg), 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (109 mg) and iPr2NEt (0.119 mL). The mixture was stirred at r.t. for 16 hours before all the solvents were removed under vacuum. The residue was dissolved in dichloromethane (5.00 mL) and 2 mL of TFA. The mixture was stirred at r.t. for 3 hours. All solvents were removed under vacuum and the residue was purified by prep. HPLC to give ethyl 1-(4-(4-(4-aminobutylcarbamoyl)phenylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)cyclopropanecarboxylate (80 mg).
