실험 절차

Combine 4H-3-thia-4,9-diaza-benzo[f]azulen-10-ylamine (1.26 g, 5.85 mmol), (S)-2-(2-methoxy-ethyl)-piperazine (2.53 g, 17.56 mmol), DMSO (4.0 ml), and toluene (16.0 ml). Stir and heat the mixture at 105° C. After 24 hours, cool the mixture to ambient temperature. Dilute the mixture with ethyl acetate and wash the organic layer with 0.1N NaOH and brine. Dry (sodium sulfate) and concentrate the organic layer to residue. Purify the residue on silica gel using a gradient of dichloromethane to dichloromethane/methanol (85:15) to give 395.8 mg (20%) of an brown foam: mass spectrum (ion spray): m/z=343.1 (M+1).
