Mode opératoire

Suspend 6-fluoro-2-methyl-4,9-dihydro-3-thia-4,9-diazabenzo[f]azulene-10-thione (500 mg, 1.9 mmol) in dichloromethane (30 ml), stir under nitrogen and cool in an ice/water bath. Add methyl trifluoromethanesulfonate (500 μl), and stir overnight. Concentrate the reaction mixture under reduced pressure, take up in pyridine (10 ml) and add (S)-2-(2-methoxyethyl)piperazine (400 mg, 2.78 mmol) and stir the reaction mixture under nitrogen and heat at 90° C. for three days. Concentrate the reaction mixture under reduced pressure and purify by flash column chromatography on silica gel (eluent dichloromethane/methanol) to give the desired as a yellow solid 727 mg: Mass Spectrum (FIA) 375 (M+1).
