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-[(1,2,3,4-tetrahydroisoquinolin-5-yloxy)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 (0.015 g, 33%) as an amorphous white solid. 1H NMR (500 MHz, DMSO): δ 7.79 (s, 1H), 7.71 (m, 2H.), 7.67 (d, 1H), 7.52 (t, 1H), 7.20 (s, 1), 7.05 (t, 1H), 6.96 (d, 1H), 6.83 (d, 1H), 6.70 (bs, 1H.), 6.02 (s, 2H.), 5.10 (s, 2H), 4.61 (m, 2H), 3.54 (m, 4H), 2.96 (s, 4H), 2.74 (m, 2H.), 2.44 (m, 2H.), 2.18 (s, 3H). (NMR sample heated to 90 c); Analytical LCMS (M+H)+: m/z=534.1.
