Reaction Steps

N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (20 mg, 0.05 mmol) and N,N-diisopropylethylamine (10 uL, 0.07 mmol) were added to a solution of 2-amino-4-(4-methylpiperazin-1-yl)quinazoline-7-carboxylic acid (10 mg, 0.03 mmol) and 3-{[(8-amino-5,6,7,8-tetrahydronaphthalen-2-yl)oxy]methyl}benzonitrile HCl salt (30 mg, 0.07 mmol) in N,N-dimethylformamide (1 mL) at r.t. The reaction was stirred for 2 h. and the product was purified without workup by RP-HPLC (pH=10) to afford the desired compound (0.013 g, 30%) as an amorphous white solid. 1H NMR (400 MHz, DMSO): δ8.84 (d, 1H), 7.77-7.6 (m, 5H), 7.46 (dd, 1H), 7.42 (m, 1H), 6.99 (d, 1H), 6.80 (dd, 1H), 6.74 (m, 1H), 6.36 (bs, 2H), 5.12 (m, 1H), 5.02 (s, 2H), 3.51 (bs, 4H), 3.27 (s, 4H), 2.62 (m, 2H), 2.17 (s, 3H), 1.88 (m, 2H), 1.70 (m, 2H). Analytical LCMS (M+H)+: m/z=548.1.
