Reaction Steps

To a solution of 8-(1H-Pyrazol-4-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene-2-carboxylic acid (363.8 mg, 1.161 mmol) in N,N-dimethylformamide (39-60 equiv.) and N,N-Diisopropylamine (1.5 equiv.) was added 2-(isopropylamino)ethanol (133.1 mg, 1.29 mmol) followed by the addition of N,N,N′N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uranium hexafluorophosphate (1.1 equiv.). The reaction mixture was heated at 50° C. for 2 hrs to 24 hours depending on when complete by LCMS. Reaction mixture was concentrated on the genevac and purified by HPLC or diluted with ethyl acetate, washed with brine, dried over sodium sulfate and concentrated in vacuo prior to purification by HPLC to give 103 (70 mg, 15% yield, M+1 399.1)
