Diisopropylethylamine → 4-{3-[1-(1,3-benzothiazol-6-yl)cyclopropyl][1,2,4]triazolo[4,3-b][1,2,4]triazin-6-yl}-N-{(1S)-1-[(dimethylamino)carbonyl]propyl}benzamide

Participants

Reaction Steps

N,N-Diisopropylethylamine (14 μL, 0.080 mmol) was added to a mixture of 4-{3-[1-(1,3-benzothiazol-6-yl)cyclopropyl][1,2,4]triazolo[4,3-b][1,2,4]triazin-6-yl}benzoic acid (11 mg, 0.026 mmol), (2S)-2-amino-N,N-dimethylbutanamide hydrochloride (5.8 mg, 0.034 mmol) and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (14 mg, 0.032 mmol) in DMF (0.4 mL). The mixture was stirred at RT overnight. The residue was diluted with methanol, and purified by RP-HPLC (pH=10) to afford the desired product. Analytical LCMS: (M+H)+=527.0
