Participants

Reaction Steps

1-{4-[1-(Cyclopropylmethyl)-4-(trifluoromethyl)-1H-benzotriazol-5-yl]phenyl}methanamine (19 mg, 0.055 mmol), L-lactic acid (9.9 mg, 0.11 mmol, 2 equiv), N,N-diisopropylethylamine (48 μL, 0.27 mmol, 5 equiv) and (1H-benzotriazol-1-yloxy) (tripyrrolidin-1-yl) phosphonium tetrafluoroborate (43 mg, 0.082 mmol, 1.5 equiv) were combined in dichloromethane (1.5 mL) and stirred for 15 minutes. The mixture was concentrated in vacuo and the residue was purified by preparative reverse phase HPLC (95:5 to 5:95; water containing 0.1% trifluoroacetic acid:acetonitrile containing 0.1% trifluoroacetic acid), providing the titled compound: 1H-NMR (400 MHz, d6-DMSO) δ 8.33 (1H, t, J=6.9 Hz), 8.30 (1H, d, J=8.5 Hz), 7.51 (1H, d, J=8.7 Hz), 7.36-7.32 (4H, m), 4.72 (2H, d, J=7.2 Hz), 4.41-4.33 (2H, m), 4.08-4.03 (1H, m), 1.46-1.38 (1H, m), 1.27 (3H, d, J=6.6 Hz), 0.60-0.55 (2H, m), 0.53-0.50 (2H, m) ppm; high resolution mass spectrometry (ES+) m/z 419.1700 [(M+H)+; calculated for C21H22F3N4O2: 419.1689].
