実験手順
Combine 2-isopropyl-4H-3-thia-4,9-diaza-benzo[f]azulene-10-ylamine hydrochloride (0.31 g, 1.04 mmol) and (S)-2-(2-methoxy-ethyl)-piperazine (0.30 g, 2.08 mmol) with anhydrous pyridine (4 mL), heat to 110° C. and stir overnight. Cool to ambient temperature to give crude material. Purification by cation exchange chromatography, eluting with solutions of 2M ammonia in methanol, in dichloromethane, (2%, 5%, 10%), and 2M ammonia in methanol, followed by flash chromatography, eluting with a gradient of solutions of 2M ammonia in methanol, in dichloromethane (2-4%), to give the title compound: mass spectrum (APCI, m/e): 385 (M+1); NMR (1H, 300 MHz, DMSO-d6),δ (ppm): 7.60 (s, 1H), 6.86-6.73 (m, 3H), 6.67 (m, 1H), 6.30 (s, 1H), 3.78 (m, 2H), 3.38-3.33 (m, 2H), 3.19 (s, 3H), 3.01-2.60 (m, 6H), 2.39 (m, 1H), 1.51 (m, 2H), 1.17 (d, 6H, J=7.5 Hz).
