Participants

Reaction Steps

N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (26 mg, 0.070 mmol) was added to a solution of 2-amino-4-(4-methylpiperazin-1-yl)quinazoline-7-carboxylic acid (10 mg, 0.03 mmol) in N,N-Dimethylformamide (1 mL) and N,N-Diisopropylethylamine (12 uL, 0.070 mmol). The reaction was stirred for 10 min., and the 2-biphenyl-4-yl-1-(1,3-thiazol-2-yl)ethanamine (20 mg, 0.070 mmol) was added. The reaction was stirred for 1 h. at r.t. The final product was purified by prep RP-HPLC (pH=10) to afford the desired compound (0.003 g, 20%) as an amorphous white solid. Analytical LCMS (M+H)+: m/z=550.0.
