反応手順

A 5 mL microwave vial was charged with Compound 157 (290 mg, 0.79 mmol), 3-(dimethylamino)propyl-4-methylbenzenesulfonate (224 mg, 0.87 mmol), potassium carbonate (218 mg, 1.58 mmol) and 2 mL of anhydrous DMF, under nitrogen atmosphere. The reaction mixture was heated at 200° C. for 30 min. in microwave with high absorption. The reaction was quenched with addition of water, and the solid precipitate out was collected by filtration and purified through preparative HPLC to provide title compound (1438 mg, 40%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.17 (t, J=7.33 Hz, 3H) 1.99 (qd, J=6.61, 6.44 Hz, 2H) 2.20 (s, 6H) 2.26 (s, 3H) 2.53-2.56 (m, 2H) 3.41 (q, J=7.33 Hz, 2H) 4.25 (t, J=6.19 Hz, 2H) 7.05-7.09 (m, 1H) 7.11-7.14 (m, 1H) 7.54 (d, J=1.52 Hz, 1H) 7.85 (t, J=7.83 Hz, 1H) 7.98 (t, J=6.95 Hz, 2H) 8.06-8.08 (m, 1H) 8.27 (d, J=1.77 Hz, 1H) 12.13 (s, 1H); [M+H] calc'd for C25H30N3O3S, 452.2; found, 452.4.
