반응 단계

Combine 7-chloro-4H-3-thia-4,9-diaza-benzo[f]azulen-10-ylamine hydrochloride (786.7 mg, 2.75 mmol), (S)-2-(3-methoxy-propyl)-piperazine (870.0 mg, 5.50 mmol), DMSO (2.0 ml), and toluene (8.0 ml). Stir and heat the mixture at 105° C. After 48 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 (90:10) to give 280.3 mg (26%) of the title compound: mass spectrum (ion spray): m/z=391.1 (M+1).
