Procedimiento

2-bromo-1-(10H-phenothiazin-10-yl)butan-1-one (3.675 g, 25 mmol) and 5H-[1,2,4]triazino[5,6-b]indole-3-thiol (2.125 g, 25 mmol) were dissolved in 50 ml anhydrous DMF and cooled to 0° C. 11.1 ml Et3N (250 mmol) was dropped to the above mixture. After stirring for 1.5h, TLC indicated that the reaction was completed and stopped. 300 ml ethyl acetate was added to the reaction mixture. The organic phase was washed by saturated NH4Cl for five times. It was dried by anhydrous Na2SO4 and filtered. The organic phase was concentrated to about 15 ml and the pale solid was formed. The amorphous solid was collected and washed by a few ethyl acetate. 1H NMR (500 MHz, DMSO-d6) δ; 12.63 (br, 1H), 8.34 (d, J=7.5?, 1H), 7.89-7.96 (m, 1H), 7.56-7.73 (m, 4H), 7.37-7.47 (m, 5H), 7.29-7.22 (m, 1H), 5.27 (t, J=7.0, 1H), 1.86 (br, 1H), 1.74 (br, 1H), 0.85 (br, 3H). 13C NMR (125 MHz, DMSO-d6) δ 170.0, 146.8, 141.7, 140.9, 138.5, 138.3, 131.4, 128.6, 128.2, 128.0, 127.7, 127.4, 123.0, 122.0, 118.0, 113.2, 31.1, 25.9, 11.8. HRMS was calculated for C25H19N5OS2 469.1031 and found 469.1047.
