Procedure

To a solution of the acid from step (b) above (0.48 g, 2 mmol) in DMF (20 mL) was added 3,4-diaminobenzotrifluoride (0.354 g, 2 mmol, Lancaster), followed by N,N-diisopropylethylamine (0.516 g, 4 mmol, Aldrich) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.912 g, 2.4 mmol, Aldrich). The reaction mixture was stirred at room temperature for 16 h, and then concentrated in vacuo. The residue was dissolved in EtOAc and the organic solution was washed with saturated NaHCO3 and brine, dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by silica gel chromatography, eluting with hexane/EtOAc (3:7) to give the title compound as a purple solid. MS (ESI, pos. ion) m/z: 399 (M+1).
