Reaction Steps

To a 4 mL screw-cap vial was added 4-amino-6-(3-fluorophenyl)quinazoline-8-carboxylic acid (0.10 mmol, 28 mg) followed by N-(2-aminoethyl)acetamide (2 equiv., 0.20 mmol, 20 mg), HATU (1.1 equiv., 0.11 mmol, 43 mg), dimethylformamide (0.5 mL), and triethylamine (3 equiv., 0.30 mmol, 0.042 mL). The reaction was capped and shaken at 50° C. for 4 h. The reaction was cooled to room temperature, diluted with 2.5 ml dichloromethane and washed with 1 ml water. Organic was concentrated, then the crude was purified by reverse phase HPLC, yielding 6 mg of desired product. 1H NMR (400 MHz, DMSO) δ 11.17-11.07 (t, J=5.6 Hz, 1H), 8.89-8.75 (m, 2H), 8.54-8.50 (s, 1H), 8.44-8.06 (m, 2H), 8.06-7.99 (t, J=5.5 Hz, 1H), 7.75-7.64 (m, 2H), 7.64-7.53 (m, 1H), 7.35-7.22 (m, 1H), 3.53-3.44 (m, 2H), 3.32-3.26 (m, 2H), 1.85-1.82 (s, 3H). LCMS M/Z (M+H)=368.
