Participants

Reaction Steps

N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (0.030 g, 0.078 mmol) was added to a solution of methyl 4-[3-(aminomethyl)phenoxy]benzoate-HCl (0.045 g) and 2-amino-4-(4-methylpiperazin-1-yl)quinazoline-7-carboxylic acid (0.015 g, 0.052 mmol) in N,N-Dimethylformamide (1.0 mL) with N,N-diisopropylethylamine (0.027 mL, 0.16 mmol) at r.t. The reaction was stirred for 1 h. The product was purified without workup by RP-HPLC (pH=10) to give the desired product (0.020 g, 50%) as a white amorphous solid. 1H NMR (400 MHz, DMSO): δ 9.16 (m, 1H), 7.89 (d, 2H), 7.70 (m, 2H), 7.36 (m, 2H), 7.14 (d, 1H), 6.99 (d, 2H), 6.95 (m, 2H), 6.39 (bs, 2H), 4.44 (d, 2H), 3.75 (s, 3H), 3.50 (bs, 4H), 3.29 (s, 4H), 2.18 (s, 3H); Analytical LCMS (M+H)+: m/z=527.0.
